User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b3) Gecko/20050713 Firefox/1.0+
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b3) Gecko/20050713 Firefox/1.0+

With the supplied simple test case URL, the combination of an iframe with a page
which links to another page that contains a javascript focus() on window.onload
causes background repaint issues on back (when bfcache is enabled).  See the URL
for more details.

Reproducible: Always

Steps to Reproduce:
1. Visit test case URL
2. Click on link inside iframe
3. Press back

Actual Results:  
The background of the initial iframe page is incorrect (black in windows, static
garbage in linux).

Expected Results:  
The background should be normal (white).

Confirmed, changing status to new. This bug does not occur with bfcache disabled.

Has this always been broken with fastback enabled or is this a recent problem?

I'm not sure, I only started using the trunk builds again a few days ago.

Please attach the testcase to the bug so it doesn't go away?

This appears to WFM with the latest pacifica build. Adrian, can you confirm?

Yup, it looks like it WFM in the hourly linux build.  However, here's another
unrelated bug I've noticed (again with bfcache):
- open up a new window
- go to any page
- now go to the test url (http://devrandom.com/test/firefox/iframe.html)
- click on the link to go to the 2nd iframe page
- go to any page
- now if you press back 3 times to go back to the first page everything is fine...
- however, if you go forward to the test page, you get the 2nd iframe page
instead of the 1st one.
- go forward again and you get the 2nd iframe page (correct)
- go forward, then back and you get the 1st iframe page instead of the 2nd. 
from there it alternates between the two.

I guess I need to file another bug for this one.
