Also even if every app on this planet supported it properly, you should still listen to the users. If they feel like it's wrong that the menu is disconnected from the applications main window, you can come along and go "but most apps have multiple windows and the actions in the menu are application specific, not window specific" and feel really smart about it, or acknowledge that this might be an artificial rule that while technically correct still leads to inferior UX. Because our simple dummy brains just get more confused by the fact that this menu seems entirely disconnected from the application than they would by the fact that the menu is arbitrarily fused to a random window of the application. Really most of the time it's not even that random because many apps have just one main window while the others are tool boxes, settings windows or other dialogs you only open occasionally for a short moment.
