WFM with e10s on/off.

Did you test with e10s enabled?

I have had this happen intermittently to me where a plugin from 1 tab shows up in another tab after switching tabs.  Sometimes its the actual plugin and I can interact with it, and other times it's just a static image of the plugin. I was just able to reproduce it using Hulu.com and a blank new tab (see attachment).  I could have sworn that there was already a bug filed on this, but I can't for the life of me find it.

STR:
1) Play a video on Hulu.com
2) Open a new tab (doesn't have to be blank)
3) Switch between the 2 tabs as many times as needed.

It happened maybe 1 in 20 times when I was sitting here doing nothing but trying to reproduce.

:jimm, if I remember correctly, you refactored the code for plugin bounds a few months ago for e10s.  Any ideas?
