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.

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.
