[Reg 6.5.6->6.7.2] QML text input, e.g. TextInput, does not integrate well with Android system built-in keyboard

Reproducer attached. It is actually the same issue as QTBUG-128377. But since it is QML-based, I think it is better to separate them.

Similar procedure to reproduce the issue:
Good behavior (6.5.6):
1. Upon clicking TextInput so that it is focused, only digit keyboard pops up. Because "Qt.ImhDigitsOnly" says so.
2. The entire window is shifted upward a little bit, so that TextInput is not covered.

Bad behavior (6.7.2):
1. Upon clicking TextInput , it is still full keyboard.
2. No shift happens and TextInput is completed covered. One can't see what's being input.
