Embed YT vids with invisible controls buttons

[Semtex]

This is bug, which I see since latest dev NS build, be sure that NS is enabled, visit this address: http://www.wiocha.pl/1333124,Marcin-Roz ... temat-haha
In YT vid control buttons are invisible.
Disable NS, visit link one more time- no problem.
To reproduce use link from above, if You restart browser on tab with link from above controls will appear.
Latest Nightly and latest NS dev.

Can someone confirm this bug, since I see this on every page with embed YT videos, I don't know if this is local or global. Thanks. If local, then I can look for problem on my side.
Still persists in latest NS dev version. Looks like there is problem with embed vids on non HTTPS sites, then controls are missing.
Here is international site with this problem http://www.windowscentral.com/instagram ... book-login
Look at embed video there, looks like this on my end:

When NoScript disabled then working fine again

Confirmed, on the first link.
Or actually not.
Well, kind of.

Something very odd going on?

On the second link, I can only "see" the timeline, E.T., & the volume bar (on mouseover).
I cannot actually see the play, pause, fullscreen ... buttons - regardless of NoScript or not.


(Initially I started out in Allow Global. On Forbid Global, the video continued to play. I had to manually refresh the page before it registered "enable JavaScript if it is disabled in your browser".)


And now both are showing full controls, fully visible, & I can't break it again.
(HSTS perhaps?)


SeaMonkey 2.40.
NoScript

To trigger this bug You need to always close old tab and open new one, when testing with NS enabled and disabled. If You use "old" tab, before restart then this problem don't persist. That is why it is bit more complicated and very annoying.
