Fix stack overflow when opening child dialog from notification center#17261
Merged
Conversation
Disable TrapFocus on the notifications center dialog because it launches child dialogs. When multiple dialogs trap focus simultaneously, a recursive focus loop occurs causing 'Maximum call stack size exceeded' errors. Fixes #16593

Summary
Fixes #16593
When clicking "View Response" from the Notifications Center dialog, a child dialog (TextVisualizer) opens. Because both dialogs have focus trapping enabled, the Fluent UI focus-trap handlers recurse infinitely between them, causing
RangeError: Maximum call stack size exceeded.Fix
Hide the parent notification center dialog while the child dialog is open, then restore it after the child closes. This prevents multiple dialogs from competing for focus simultaneously.
Changes
