[QtDeclarativeCamera] Popup list of available cameras is not available after changing the orientation

Steps to reproduce:

1. Open Qt Declarative Camera example https://doc.qt.io/qt-6/qtmultimedia-declarative-camera-example.html 
2. Build and run the app on an Android device.
3. Tap on the button to show a list of cameras in landscape mode, change the orientation to portrait and try to open the list again.

Expected: The list is visible.

Actual: Cannot show the list in portrait mode (attaching the recording). It seems that positioning is incorrect, but I was not sure if it was with the example implementation or handling the popup position in QML itself. Further investigation is needed.

Reproducibility:  100%
