    Description

      Under some circumstances the application crashes with the "QulError_PropertyBase_FirstDependencyAlreadySet" error. The bug can be reproduced by rapidly changing the states which include animations with transitions.

      Way to reproduce:
      1) Build the attached example against some affected version of the Qt for MCUs (Desktop kit recommended, happens on actual device as well).
      2) Run the application
      3) Click very fast inside the window until it fails. It usually takes about 10 seconds. (Recommended using two fingers with mouse, clicking too slowly hides the bug)

      Please find the call stacks from the desktop and from the device attached as images.
