IME composition when focus moves between elements (Korean and others)

If the user switches focus to another field, button, or nested contenteditable while Korean (or other) IME composition is active, browsers differ on whether composition is committed, cancelled, or leaves orphan state. Chrome, Safari, and Firefox do not agree; mobile adds more variance.
