           Summary: onwebkitfullscreenchange present, but not firing in
                    iOS 12 when target is video element
           Product: WebKit

Hello,

iOS 12 Safari/Webkit introduces support for the `document.onwebkitfullscreenchange`. While this event seems to work when non-video elements request fullscreen, it does not work with the `<video>` element. Here is an example that requests full screen on a `<div>` and `<video>`, and console.logs when `onwebkitfullscreenchange` is fired: https://jackwellborn.com/playground/videoFullScreenTest.html. The example fires `onwebkitfullscreenchange` for both the div and video in Desktop Safari Technology Preview (Release 63 (Safari 12.1, WebKit 13607.1.2.1)) as expected, but only fires it for the div in iOS 12 Public Beta 8 or 9. Let me know if you need any more clarification or have follow questions.

Thanks.

~Jack
