Description David Carson 2011-05-31 17:58:56 PDT 
If the author of the content specifically set the iframe size to zero, then the frame should not be resized.
eg:
<iframe src="/fd/fb/r?v=6_12_0_776292&amp;sId=0" height="0" width="0"></iframe>

This issue can be seen on the Bing site.

proposed patch and test case

The test results should be platform independent (use layoutTestController.dumpAsText()).  r- for that.

The patch itself looks good. I'm pretty sure we were not flattening zero-sized frames in the past, wonder how that got lost?

The way the test stands today, it clearly shows that the iframe is not flattened as we dump the DOM sizes. Changing to layoutTestController.dumpAsText(), I'll need to use script to grab the element sizes and print them.
