    Description

      This works only if any js is invoked.

      See the bug in action: IyqhZotKL8.mp4

      Repo: https://gitlab.com/kelteseth/ScreenPlay

      Internally it uses LIST_PROPERTY macro that is defined herem that is a wrapper around QQmlListProperty  https://gitlab.com/kelteseth/ScreenPlay/-/blob/master/ScreenPlayUtil/inc/public/ScreenPlayUtil/ListPropertyHelper.h#L58

      If it helps, I could recreate this issue in a test project.
