Pausing and resuming Q4A apps can start the virtual keyboard

Pausing and resuming Android apps works a bit funkily if the user interacts with the application. Tapping on the app content, whether the element is interactable or not, causes the virtual keyboard to appear after the app is moved to the background and back to the foreground.

Regression from Qt 6.6

The logs don't show anything particularly worrisome or suspicious based on a quick look.

Preconditions:

• Qt 6.7.0/6.7.1
• Android emulator

Steps to reproduce:

1. Deploy example to device
2. Start example app
3. Click on an element in the example
4. Move the example to the background (for example adb shell input keyevent KEYCODE_HOME)
5. Return to the example

Strangely, this doesn't reproduce on my actual Android 13 device, only on emulators. And even there not with an AVD with a skin. But managed to reproduce with A12, A13 and A14 using the emulator. So the possibility of an emulator bug is possible.
