Setting a layout on a QDialog produces warning

      The provided example produces this warning:

      QWindowsWindow::setGeometry: Unable to set geometry 22x22-1300+676 (frame: 38x61-1308+645) on QWidgetWindow/"QDialogClassWindow" on "\\.\DISPLAY3". Resulting geometry: 54x22-1300+676 (frame: 70x61-1308+645) margins: 8, 31, 8, 8 minimum size: 22x22 MINMAXINFO(maxSize=POINT(x=0, y=0), maxpos=POINT(x=0, y=0), maxtrack=POINT(x=0, y=0), mintrack=POINT(x=38, y=61))) 


      It goes away when setting a minimum size on the dialog for this simple example but for my use case in a more complicated setup it is triggered by having a QLabel with word wrap enabled which I seem to not be able to get away from.


      I debugged it a bit and there seems to be a mismatch between the QWindows understanding of the geometry and the platform window.

       	Qt6Widgetsd.dll!QDialog::showEvent(QShowEvent * event) Line 870	C++

      In this callstack setGeometry on the widget is called with the correct size, but in the QWindow::setPosition the size returned is wrong, I assume its the size before the layout has been evaluated.
