No backport to stable for 366f9cc (AI decision).

This change modifies packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the entire new-trace-viewer directory does not exist on stable — it is a main-only component. The new use-reduced-motion hook is only consumed by that main-only trace viewer, so backporting would have no useful effect on stable.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

Don't do zoom animation when clicking on steps if prefers-reduced-motion is set to true for a user.

No backport to stable for 366f9cc (AI decision).

This change modifies packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the entire new-trace-viewer directory does not exist on stable — it is a main-only component. The new use-reduced-motion hook is only consumed by that main-only trace viewer, so backporting would have no useful effect on stable.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

Don't do zoom animation when clicking on steps if prefers-reduced-motion is set to true for a user.

No backport to stable for 366f9cc (AI decision).

This change modifies packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the entire new-trace-viewer directory does not exist on stable — it is a main-only component. The new use-reduced-motion hook is only consumed by that main-only trace viewer, so backporting would have no useful effect on stable.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

Don't do zoom animation when clicking on steps if prefers-reduced-motion is set to true for a user.

No backport to stable for 366f9cc (AI decision).

This change modifies packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the entire new-trace-viewer directory does not exist on stable — it is a main-only component. The new use-reduced-motion hook is only consumed by that main-only trace viewer, so backporting would have no useful effect on stable.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

Don't do zoom animation when clicking on steps if prefers-reduced-motion is set to true for a user.

No backport to stable for 366f9cc (AI decision).

This change modifies packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the entire new-trace-viewer directory does not exist on stable — it is a main-only component. The new use-reduced-motion hook is only consumed by that main-only trace viewer, so backporting would have no useful effect on stable.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

Don't do zoom animation when clicking on steps if prefers-reduced-motion is set to true for a user.

No backport to stable for 366f9cc (AI decision).

This change modifies packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the entire new-trace-viewer directory does not exist on stable — it is a main-only component. The new use-reduced-motion hook is only consumed by that main-only trace viewer, so backporting would have no useful effect on stable.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

Don't do zoom animation when clicking on steps if prefers-reduced-motion is set to true for a user.

No backport to stable for 366f9cc (AI decision).

This change modifies packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the entire new-trace-viewer directory does not exist on stable — it is a main-only component. The new use-reduced-motion hook is only consumed by that main-only trace viewer, so backporting would have no useful effect on stable.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.

Don't do zoom animation when clicking on steps if prefers-reduced-motion is set to true for a user.

No backport to stable for 366f9cc (AI decision).

This change modifies packages/web-shared/src/components/new-trace-viewer/trace-viewer.tsx, but the entire new-trace-viewer directory does not exist on stable — it is a main-only component. The new use-reduced-motion hook is only consumed by that main-only trace viewer, so backporting would have no useful effect on stable.

To override, re-run the Backport to stable workflow manually via workflow_dispatch with this commit SHA.
