Calling SDL_HideWindow on a SDL_WINDOW_FULLSCREEN_DESKTOP window will hang the application in SDL_PumpEvents for approximately 60 seconds, and will fail to hide the window properly, causing it to reappear some time later.

It looks like SDL hangs in Cocoa_SetWindowFullscreenSpace while waiting for the fullscreen transition to complete.

I've attached a minimal repro.
