    Description

      Reproducible on Windows with Qt 6.2.3

      ListView has "empty content" visible when app Window is restored down.
      Steps to reproduce:
      1. Build and run the attached example project with Qt 6.2.3
      2. Maximize app window
      3. scroll the list all the way to bottom and back to top so that the header is fully visible again
      4. Restore down the app window

      Please note, may take a few tries issue to appear.

      Expected: Header should be positioned close to top border of window
      Actual behavior: some "empty space" is visible above the ListView

      This behaves correctly if header is not used.
