In rare circumstances, the parser incorrectly parses nested tags. I have created a web page to reproduce the rare circumstances.
sometimes the simple markup:
<b> <p> a </p> </b>
is, according to firebug, incorrectly parsed as:
<b> </b><p><b> a </b></p><b> </b>
(possibly leading to incorrect CSS-Styles)
The problem seems to occur especially when the network connection is slow and firefox starts rendering before all the html is available.
i could reproduce it only if a <p>-tag is inside a typical inline tag (<a>, <b>, <i>, <em>, ...)
Reproducible: Sometimes
Steps to Reproduce:
1. go to http://chc.sbg.ac.at/bug.php
2. look at all the a's
Actual Results:
some of the a's are red
Expected Results:
all a's should be grey
The bug occurs on every configuration of Firefox i can test: Mac OS (Firefox 3.5.3 and most recent alpha), Ubuntu (Firefox 3.0.15), Windows (several versions of Firefox 2 and 3)

This is a side-effect of how our HTML parser works: it depends on packet boundaries. If you enable the HTML5 parser, it does the right thing. For more fun, reload your page a few times in a row to see how packet boundaries affect the parser. I'm duping your bug to the bug that would make us consistent, but you really want the HTML5 parser.

i'm sorry for reporting a duplicate bug. on the other hand, a search term like "Make nsHTMLTokenizer::ScanDocStructure deterministic" just didn't occur to me when I looked for possible duplicates....

Yeah, no problem. Like I said, the bug I duped this to is not *really* the proper bug to dupe it to, it's just a convenient place to stick it. This bug is really asking for us to do "residual style" parsing in a different way, which we're doing with the HTML5 parser (but I can't find the bug at the moment).
