FocusTrapScope
-
Standard "modal focus trap" for an in-tree overlay panel — wraps
child (the modal's own content) in a FocusScope that
autofocuses as soon as this widget mounts (i.e. exactly when the
overlay it belongs to appears, matching this package's "always
mounted, panel nullable" convention —
NeonDialog.overlaySlot,
PauseOverlay), and restores focus to whatever had it right BEFORE
this widget mounted, the moment it's removed from the tree again
(the overlay closing).
