class Lease

Declaration: final

Scoped keyboard-focus ownership.

Releasing an old owner cannot clear a newer focus request, including one using the same target ID. Move/release on any thread with exclusive access to this handle. Retains only routing state, not the widget/adapter. Release clears focus without restoring older requests.
