No backport to stable for ab7e5ab (AI decision).

This commit adds tooltips to the up/down navigation buttons in the new-trace-viewer component and modifies icon-button.tsx, neither of which exist on stable (verified via git ls-tree origin/stable). Since the feature being enhanced is main-only, there is nothing to backport these changes onto.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

No backport to stable for ab7e5ab (AI decision).

This commit adds tooltips to the up/down navigation buttons in the new-trace-viewer component and modifies icon-button.tsx, neither of which exist on stable (verified via git ls-tree origin/stable). Since the feature being enhanced is main-only, there is nothing to backport these changes onto.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

No backport to stable for ab7e5ab (AI decision).

This commit adds tooltips to the up/down navigation buttons in the new-trace-viewer component and modifies icon-button.tsx, neither of which exist on stable (verified via git ls-tree origin/stable). Since the feature being enhanced is main-only, there is nothing to backport these changes onto.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

No backport to stable for ab7e5ab (AI decision).

This commit adds tooltips to the up/down navigation buttons in the new-trace-viewer component and modifies icon-button.tsx, neither of which exist on stable (verified via git ls-tree origin/stable). Since the feature being enhanced is main-only, there is nothing to backport these changes onto.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

No backport to stable for ab7e5ab (AI decision).

This commit adds tooltips to the up/down navigation buttons in the new-trace-viewer component and modifies icon-button.tsx, neither of which exist on stable (verified via git ls-tree origin/stable). Since the feature being enhanced is main-only, there is nothing to backport these changes onto.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

No backport to stable for ab7e5ab (AI decision).

This commit adds tooltips to the up/down navigation buttons in the new-trace-viewer component and modifies icon-button.tsx, neither of which exist on stable (verified via git ls-tree origin/stable). Since the feature being enhanced is main-only, there is nothing to backport these changes onto.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

No backport to stable for ab7e5ab (AI decision).

This commit adds tooltips to the up/down navigation buttons in the new-trace-viewer component and modifies icon-button.tsx, neither of which exist on stable (verified via git ls-tree origin/stable). Since the feature being enhanced is main-only, there is nothing to backport these changes onto.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

No backport to stable for ab7e5ab (AI decision).

This commit adds tooltips to the up/down navigation buttons in the new-trace-viewer component and modifies icon-button.tsx, neither of which exist on stable (verified via git ls-tree origin/stable). Since the feature being enhanced is main-only, there is nothing to backport these changes onto.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:
