Item.x with transition animation changed after phone rotation

Steps to reproduce:

1. Compile the code in bug.zip and run on Android with Qt 6.2 beta1.

2. Click the small green rectangle on top, the big green rectangle's x property become 0.

3. Then rotation the phone, change the orientation from portrait to landscape or vice versa.

4. The big green rectangle's x property become the width of the window.

If we remove the transition lines from main.qml, x won't change.

Qt 5.15.2 doesn't has this bug.
