fullscreenchange event not firing in Chrome

Question

I\'m trying to monitor when the browser enters fullscreen mode.

This blog is referenced everywhere I search as the guide on the fullscreen API.

fullscreenchange events do work, but only if the fullscreen mode is triggered by requestFullscreen.

There appears to be a security restriction that prevents JavaScript from monitoring if a user manually enables fullscreen mode via a hotkey.

Alternatively, you can monitor the resize events to see if the window matches the desktop size, but this seems like a hack to me (i.e. would this work on dual-monitors?)

I decided to abandon monitoring of fullscreen mode, and just use the API to toggle the state.
