QLocalServer does not receive any messages during manual window movement

I do not receive any messages when I move a window on Windows. I discovered this behavior when dragging the ScreenPlay main window. This would suddenly stop my wallpaper because it no longer receives "keep alive pings". I reimplemented a simple QLocalSocket server client app (see QtPingFreeze.7z and was able to recreate the issue both in 5.15.2 and 6.1

1. Start the QtPingFreeze project two times (preferably with "Run in terminal" enabled)
2. Start the server
3. Start the client
4. Watch how the client sends a ping alive event every second.
5. Actively move the window. The server will no longer receive any events during movement.
