:masayuki can you investigate, please?

Although I don't know why Chrome does not exit from the full screen mode with Escape key press, Safari does it and Safari does not fire keyup only in this case too. So, I think that it's consumed by OS before we handle it. However, it could be possible to handle it with raw event hook. See bug 1299553 for the detail.

Summary: Escape key does not fire keyup → Escape key does not fire keyup when exiting from the full screen mode of macOS window
Status: UNCONFIRMED → NEW
Ever confirmed: true

In Chrome, a website-initiated fullscreen (with element.requestFullscreen()) is exited with an Esc keypress (and it doesn't fire either keydown or keyup). A user-initiated fullscreen requires you to press and hold Esc.
