On macOS when the initial "new user warning" dialog is display this breaks the application menu:

1. While the dialog is shown the main app menu is not visible, instead a menu only for the dialog is shown
2. Once the dialog is closed and the main app window is focused the application menu is properly shown, but menu items don't open on click and is unusable. Opened menu shows up quickly on a second click, but closes directly

This only happens with the Qt6 port currently in master. If launched with the new user dialog disabled the app menu behaves as expected.

The Qt5 release version behaves correctly and always shows the app menu.
