[web-shared][web] Fix detail panel re-rendering for encrypted runs during polling

[karthikscale3]

Summary

• useWorkflowResourceData: Only clear data to null when the selected span actually changes (different resource/id). Re-fetches for the same selection (e.g. encryption key reference change during polling) now keep previous data visible instead of flashing a loading skeleton.
• AttributePanel: Only show loading skeleton for input/output/eventData when there's no existing content (!hasDisplayContent), so already-fetched data isn't replaced by a skeleton during background re-fetches.

Context

For encrypted runs in a running state, polling causes encryptionKey to get a new reference each cycle. This was triggering useWorkflowResourceData to clear data and re-fetch, causing input/output to flash between skeleton and content every few seconds.

Summary

• useWorkflowResourceData: Only clear data to null when the selected span actually changes (different resource/id). Re-fetches for the same selection (e.g. encryption key reference change during polling) now keep previous data visible instead of flashing a loading skeleton.
• AttributePanel: Only show loading skeleton for input/output/eventData when there's no existing content (!hasDisplayContent), so already-fetched data isn't replaced by a skeleton during background re-fetches.

Context

For encrypted runs in a running state, polling causes encryptionKey to get a new reference each cycle. This was triggering useWorkflowResourceData to clear data and re-fetch, causing input/output to flash between skeleton and content every few seconds.

Summary

• useWorkflowResourceData: Only clear data to null when the selected span actually changes (different resource/id). Re-fetches for the same selection (e.g. encryption key reference change during polling) now keep previous data visible instead of flashing a loading skeleton.
• AttributePanel: Only show loading skeleton for input/output/eventData when there's no existing content (!hasDisplayContent), so already-fetched data isn't replaced by a skeleton during background re-fetches.

Context

For encrypted runs in a running state, polling causes encryptionKey to get a new reference each cycle. This was triggering useWorkflowResourceData to clear data and re-fetch, causing input/output to flash between skeleton and content every few seconds.

• Wall Time: Total testbench time (trigger workflow + poll for result)
• Overhead: Testbench overhead (Wall Time - Workflow Time)
• Samples: Number of benchmark iterations run
• vs Fastest: How much slower compared to the fastest configuration for this benchmark

Summary

• useWorkflowResourceData: Only clear data to null when the selected span actually changes (different resource/id). Re-fetches for the same selection (e.g. encryption key reference change during polling) now keep previous data visible instead of flashing a loading skeleton.
• AttributePanel: Only show loading skeleton for input/output/eventData when there's no existing content (!hasDisplayContent), so already-fetched data isn't replaced by a skeleton during background re-fetches.

Context

For encrypted runs in a running state, polling causes encryptionKey to get a new reference each cycle. This was triggering useWorkflowResourceData to clear data and re-fetch, causing input/output to flash between skeleton and content every few seconds.

Summary

• useWorkflowResourceData: Only clear data to null when the selected span actually changes (different resource/id). Re-fetches for the same selection (e.g. encryption key reference change during polling) now keep previous data visible instead of flashing a loading skeleton.
• AttributePanel: Only show loading skeleton for input/output/eventData when there's no existing content (!hasDisplayContent), so already-fetched data isn't replaced by a skeleton during background re-fetches.

Context

For encrypted runs in a running state, polling causes encryptionKey to get a new reference each cycle. This was triggering useWorkflowResourceData to clear data and re-fetch, causing input/output to flash between skeleton and content every few seconds.

• Wall Time: Total testbench time (trigger workflow + poll for result)
• Overhead: Testbench overhead (Wall Time - Workflow Time)
• Samples: Number of benchmark iterations run
• vs Fastest: How much slower compared to the fastest configuration for this benchmark

Summary

• useWorkflowResourceData: Only clear data to null when the selected span actually changes (different resource/id). Re-fetches for the same selection (e.g. encryption key reference change during polling) now keep previous data visible instead of flashing a loading skeleton.
• AttributePanel: Only show loading skeleton for input/output/eventData when there's no existing content (!hasDisplayContent), so already-fetched data isn't replaced by a skeleton during background re-fetches.

Context

For encrypted runs in a running state, polling causes encryptionKey to get a new reference each cycle. This was triggering useWorkflowResourceData to clear data and re-fetch, causing input/output to flash between skeleton and content every few seconds.

Summary

• useWorkflowResourceData: Only clear data to null when the selected span actually changes (different resource/id). Re-fetches for the same selection (e.g. encryption key reference change during polling) now keep previous data visible instead of flashing a loading skeleton.
• AttributePanel: Only show loading skeleton for input/output/eventData when there's no existing content (!hasDisplayContent), so already-fetched data isn't replaced by a skeleton during background re-fetches.

Context

For encrypted runs in a running state, polling causes encryptionKey to get a new reference each cycle. This was triggering useWorkflowResourceData to clear data and re-fetch, causing input/output to flash between skeleton and content every few seconds.

• Wall Time: Total testbench time (trigger workflow + poll for result)
• Overhead: Testbench overhead (Wall Time - Workflow Time)
• Samples: Number of benchmark iterations run
• vs Fastest: How much slower compared to the fastest configuration for this benchmark

Summary

• useWorkflowResourceData: Only clear data to null when the selected span actually changes (different resource/id). Re-fetches for the same selection (e.g. encryption key reference change during polling) now keep previous data visible instead of flashing a loading skeleton.
• AttributePanel: Only show loading skeleton for input/output/eventData when there's no existing content (!hasDisplayContent), so already-fetched data isn't replaced by a skeleton during background re-fetches.

Context

For encrypted runs in a running state, polling causes encryptionKey to get a new reference each cycle. This was triggering useWorkflowResourceData to clear data and re-fetch, causing input/output to flash between skeleton and content every few seconds.

• Wall Time: Total testbench time (trigger workflow + poll for result)
• Overhead: Testbench overhead (Wall Time - Workflow Time)
• Samples: Number of benchmark iterations run
• vs Fastest: How much slower compared to the fastest configuration for this benchmark
