Retain one selection-property subtree while frame presets are shown. Suspend opted-in descendant scopes after cleanup, cancel drafts before detachment can blur inputs, close portals, and release previews and pending resource work.
Track focused-element removal with VueUse so WebKit shortcuts resume after input teardown. Cover retained identity, hidden inactivity, binding rollback, async disposal, undo, popup reactivation and browser focus behavior.
