Struct FocusExitProbe 

pub struct FocusExitProbe { /* private fields */ }

Records reports that focus left a widget’s complete logical focus scope.

This probe is optional and does not change Commit-only conformance. Registry tests can use FocusExitProbe::assert_no_focus_exit after moving focus between owned controls or popup content to verify that the widget retains the complete logical scope.
