Windows Virtual Keyboard pop unexpectedly when touch occur on QML TextField

When touch occur on a TextField QML item, when echoMode "Password" or "PasswordEchoOnEdit" is set, Windows virtual keyboard show unexpectedly. When Default mode or NoEcho mode is set, nothing happen.

I don't know if the bug is keyboard pop for password mode or that keyboard doesn't pop in Default or NoEcho Mode.

In my case, the windows Keyboard is unexpected.

In some rare and undetermined cases keyboard pop doesn't occur, perhaps when the touch has given the focus to TextField item. touching repeatedly on the item make the keyboard pop every times.

this occur on Windows 10.

The bug is reproductible with touch not with mouse.

You will find attached a sample code with different cases of echoMode.
