Keyboard does not get focus on Android TV

After the fix for QTBUG-124360 - the Keyboard is opening by default when focus is set on TextField. The problem is now different:
"The Keyboard does not get focus and cannot be controlled by remote control".

I compared the current dev version and with 6.6.3.

It looks like this:

• DEV -> keyboard opens - but can't type anything (not focused?)
• 6.6.3 -> keyboard opens and can type normally
