Currently on mobile/contentEditable selection is fragile: as you double-tap or tap-drag the editor often refuses and reset selection back.
That happens because CM bails out of native 'composition', and re-renders current line. Redrawing DOM invalidates browser's native selection.
This PR relaxes this composition bailout in 2 cases:
Not only bailing out of composition in those cases is unlikely to change anything, CM's internal state will be properly updated anyway, as a result of the underlying action: changing selection.
