Description Aryeh Gregor 2012-03-14 21:04:27 UTC 
Lots of stuff refers to the viewport or initial containing block.  It's not clear whether these exist in a display: none iframe.  Here's a test-case that illustrates a problem that just bit me:

data:text/html,<!doctype html>
<iframe style="display:none"
onload="this.style.display = ''"
src='data:text/html,<!doctype html>
<body style="height:1000px">
<script>scroll(0,200)</script>
'></iframe>

In Firefox 14.0a1 and Chrome 19 dev, the iframe isn't scrolled.  In Opera Next 12.00 alpha, it is.  IE 10 Developer Preview doesn't support data: as the source for iframes, but I think it's not scrolled here.  But a similar case in Chrome did scroll.  What should happen here?

reassign to myself; apparently i am not the default assignee for this component

I think I'll hook into HTML's "being rendered" for this, and I filed https://www.w3.org/Bugs/Public/show_bug.cgi?id=22040 to make it cover the display:none iframe case.

(Turns out I didn't need "being rendered".)
