PropertyChanges behaves differently from big Qt

It seems like PropertyChanges (or State?) behave differently from the ones in big Qt.

I have two projects, one works with Qt 6.6.0 Desktop and the other with Qt for MCUs 2.6.0 Desktop.

Both are attached to this ticket. (respectively, OvenMid_Qt6.zip and OvenMid_MCU.zip)

Here is the reproduction steps:

1. Launch the app and click on the "START" button in the center.
   
2. Click on "More"
   
3. Click on the return button at the top left
   
4. At this point, in the QUL app, the screen goes back to the original active state, but in the big Qt app, the screen doesn't transition.

The issue seems to be that in QUL app, the properties set in PropertyChanges get reset when the app goes out of the particular state while in big Qt the properties need to be explicitly set.
