I can confirm this on today's build, but I suggest assigning this to a more specific product and component if anyone's going to see it. Seems like Core/HTML:Parser might be a good place.

Can this be considered a duplicate of bug 179596?

Comment 4

[Hannes Nagel]

I can confirm this Bug on FF 3.0.4 and simplify the test code. There is no table or complicated structure that causes the problem, the following is enough:

Reproduce: render following (W3 conform) html code
<h1>Example</h1>
<ul>
  <li>
</ul>

<h1>Problem</h1>

Result: The bullet is displayed in the second heading.

Expected Result: Heading is displayed below the bullet (vertical space).

Reporter, are you still seeing this issue with Firefox 3.6.x or later in safe mode? If not, please close. These links can help you in your testing.

As stated in comment 3, I'm considering this to be a duplicate of bug 179596. The test case is very similar (in the sense of empty list items triggering the symptom) and also Tyler hints towards this issue being fixed and my tests confirm it as well, both for stable 3.6.8 [1] and nightly 4.0b5pre
[2], on Windows Vista SP2.

Note that I have added a similar comment in bug 179596 comment 29.
