I am experiencing this same issue as described here.  
[https://meta.discourse.org/t/youtube-fullscreen-button-transfers-you-to-another-post-in-topic/41420](https://meta.discourse.org/t/youtube-fullscreen-button-transfers-you-to-another-post-in-topic/41420)

The topic was locked due to “cannot reproduce” so here is some more specific information.

Reproduction scenario:

play any video in this thread and go full screen  
Chrome 51.0.2704.106 m  
Works in Firefox  
[http://www.hitmanforum.com/t/elusive-target-5-the-gun-runner/8635/2](http://www.hitmanforum.com/t/elusive-target-5-the-gun-runner/8635/2)

I have found that viewport size influences the bug.  
on smaller screens the functionality works fine. on large screens the bug manifests itself.

I suspect it has to do with html elements overlapping the video player in certain responsive layout states.

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 frowning 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.
