I have an example project that uses desktop_multi_window to main three windows, one main and two others. When I click the close box of the main window it sends PostQuitMessage to quit the whole app. This works, but instead of being instantaneous, it takes about 10.5 seconds.
The issues is specific to Windows (11). On Mac Intel Sequoia, the problem is not present.
Reproduce Steps
The example project is at https://github.com/mauricev/flutter_windows_multi_engine_delay_bug
Expected behavior
The app should quit immediately
