I cannot reproduce this on OS X 10.10 with either Aurora or Nightly. Is it something specific to 10.9? adalucinet, can you reproduce this on other versions of OS X?

I can also reproduce this in 47 on 10.11.4.
Hmmm, wait, so you mean the browser full screen mode, not fullscreen video or something? I misunderstood the scope of this bug.
