Details

I /think/ doing this should be almost trivial.  The current setup looks like

 <window>
  <iframe remote>
 ---[process boundary]---
    <remote content>

We should instead be able to just do

 <window>
   <iframe remote src="proxy.html">
 ---[process boundary]---
     <iframe remote>
     ---[process boundary]---
       <remote content>

The proxy page would have no background/margins/borders/style and just contain an unstyled <iframe remote>.

We would then have to add a reftest-content-proxy.js testing script that bounced messages between reftest.js and reftest-content.js.
Blocks: fission
No longer blocks: oop-frames

Reftests should work with fission. We have a special path for taking snapshots that reftests use with e10s called WIDGET_LAYERS [1]. This path gets the snapshot from the compositor which will contain all content from OOP-iframes.
