Steps to reproduce the problem:
1. Open the link above
2. Fullscreen the embedded Youtube player

What is the expected behavior?
The youtube player is shown in the fullscreen

What went wrong?
The youtube player is constrained within its ancestor.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No 

Did this work before? No

Does this work in other browsers? Yes. Both webkit and blink show this error, but firefox renders correctly.

Here's a reference to the same bug in chromium's tracker: <a href="https://bugs.chromium.org/p/chromium/issues/detail?id=501246">https://bugs.chromium.org/p/chromium/issues/detail?id=501246</a>
