QWindow::startSystemResize STILL doesn't work on Windows

This issue relates to https://bugreports.qt.io/browse/QTBUG-82191

I have a QML window, and resizing invards sometimes gives this debug message:

 Invalid edges QFlags<Qt::Edge>() passed to QWindow::startSystemResize, ignoring.

while the user is blocked from resizing.

I can reproduce it occasionally by resizing right edge inward after making the window visible (immediately after starting the program), but more reliably by resizing inward on bottom edge then resizing inward on right edge (which will fail and keep failing until user clicks somewhere else).

Since the error happens prior to the platform-based resize, the platform should be irrelevant.
