Cannot reset text on TextEdit/Input on Android (possibly iOS)

See related discussions on QTBUG-49503

When you are typing the first word in a Text box with platform suggestions enabled, there is no way to clear the displayed text, for example with a clear button. You cannot set text = "" because no text has been committed yet, and calling Qt.inputMethod.reset() does reset the text used by the inputMethod for predictions, but does not reset the displayed text.
