I was able to reproduce and what seems to be happening is Chrome briefly resizes the discourse window beneath to fullscreen before applying the video. I’m pretty sure [it’s this bug](https://bugs.chromium.org/p/chromium/issues/detail?id=460709&q=youtube%20fullscreen&colspec=ID%20Pri%20M%20Week%20ReleaseBlock%20Cr%20Status%20Owner%20Summary%20OS%20Modified) which has been around for over a year ☹

In terms of a workaround, I don’t think there’s anything we can do as the fullscreen code is triggered within the iframe, which is outside of our security context.
