Fullscreen borderless window does not exit on MacOS

[odanek]

When window is created in the Fullscreen::Borderless mode setting control_flow to ControloFlow::Exit does not exit the event loop:

use winit::{
    event_loop::{ControlFlow, EventLoop},
    window::{Fullscreen, WindowBuilder},
};

fn main() {
    let event_loop = EventLoop::new();
    
    let window = WindowBuilder::new()
        .with_fullscreen(Some(Fullscreen::Borderless(None)))
        .build(&event_loop)
        .unwrap();

    event_loop.run(move |_, _, control_flow| {
        *control_flow = ControlFlow::Exit;
    });
}

Commenting out the .with_fullscreen(...) line does correctly exit the event loop.

Reproduced on:
winit 0.26.1
rustc 1.60.0
MacOS 12.3.1
MacBook Pro M1

Can't reproduce on macOS Mojave 10.14.6, but may have been fixed in #2292, could I get you to check?

@madsmtm I can confirm that the issue is fixed on master. It probably wasn't fixed by #2292 though because I wasn't able to reproduce the issue even using the commit before the #2292 merge.

It would be nice to know which commit fixed it, would you mind running a git bisect to figure out which one? If you can't be bothered, that's also fine!

[odanek]

@madsmtm I have checked again and it has been indeed fixed by #2292, commit 4c39b31. Sorry for the confusion.

Wonderful, thanks for your help!
