User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6

Attached are 3 test cases. The first one works fine i.e. when you press the 
test button, the iframe shows the content correctly. In the second one, the 
iframe does not seem to display anything. If you refresh the page the content 
will appear !? The third test case is an HTML file which shows the content 
correctly when opened directly in Firefox.

Reproducible: Always

NB: Open the first attachment in IE6 SP2 and press the test button -> You get 
a nice crash!

It's invalid HTML, that never should but sometimes can crash a browser, if bugs
do allow this.

Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.8b4) Gecko/20050729 SeaMonkey/1.0a
did show all as intended, in Opera8.01 the first testcase didn't work.

It indeed is invalid HTML. I filed this bug because of the discrepency between 
test case #1 and what you see if you load the HTML file directly in the 
browser (it *should* be identical)

We found this bug when a customer of ours complained about an HTML email that 
was not being displayed...

So I am thinking this bug is fixed on the trunk. Reporter, please try Deer Park
Alpha 2 (Firefox 1.5 alpha) and verify that this problem is fixed. Thanks!

Fixed is only for bugs in which the code change which fixed the problem is
known. Reopening to resolve WFM. 

Also you should not verify your own bug resolutions, but leave it for someone
else to verify that the resolution was correct.
