Note there are two list bullet points visible, but I can't see why the second one is present. This bug is filed on behalf of someone on IRC who is seeing this. I don't know enough html to say whether this 2nd bullet should be present, but it's not on Opera 9.22 or IE 6. Code is Valid XHTML 1.0 Transitional! This bug may be a dupe, but I don't know what to search for to find it. testcase to follow
Created attachment 353551 [details] testcase with divs This seems unrelated to lists, same result with <div>.
I filed bug 470118 on attachment 353551 [details]. It's somewhat related to this bug (it's showing that we're applying 'padding-left' twice, but also showing bug 470118), but perhaps it should be a separate, dependent bug. It's probably ok as one bug for now, but don't add extended commentary on that testcase.
This was fixed by the patch in bug 481769.
