- Abort firing blur events on the document and/or window if one of the blur handlers focuses something else. This ensures that the caret doesn't get confused about whether it should be active.
- Release any mouse or key grab when the view manager sees a deactivate event; this fixes event targeting when a mousedown handler opens a modal dialog.
- Make sure the editor element is actually focused before activating the caret. Just receiving a focus event isn't good enough, since a focus change does not cancel propagation of the original event.
