See the test case attached. It was displayed properly in Firefox 0.8 (not tested in Mozilla 0.6 through) but not Firefox 0.9 RC and Mozilla 1.8a. Reproducible: Always Steps to Reproduce: 1. Create a HTML document with a horizontal rule (<hr>) with CSS of border:0 and height:.08em 2. Add one or two floating elements (e.g. image) next to that horizontal rule. 3. Open the HTML in Firefox 0.9 RC or Mozilla 1.8a. See how other elements are laid properly while the horizontal rule gains extra left margin. Actual Results: The horizontal gains extra left margin. The more the float elements, the more the left margin. Expected Results: It should not add any left margin, just laid it out as other elements (e.g. paragraph).
This looks a lot like bug 244932 (which itself could be a duplicate also)
Martijn, you are right. It looks so similar... The horizontal rules just go crazy when they see floats... P.S. This is my site which is facing this problem: http://minghong.dyndns.org:8080/OpenWiki/

this regressed between linux trunk builds 2004011708 and 2004011808, apparently bug 52916
Still reproducible in Mozilla 1.8a6. And FYI, IE 6.0 and Opera 8.0 render pretty consistently. For IE, the horizontal rule always stay away from the floating element; while for Opera, the horizontal rule always go through the floating element. I'm not sure which one is the correct rendering though.

Testcase WFM using Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060817 Minefield/3.0a1 ID:2006081709 [cairo] Two of the horizontal rules are no longer visible (on my screen), but the ones that are visible no longer intersect the floated blocks. I made a local copy of the HTML Test Case and increased the height of the horizontal rules. The layout looks correct.
They all show up with non-cairo trunk build 2006-08-17-12 and are all still out of place. With a cairo build, the bottom one is missing but the remaining ones are out of place.

Works in 2006-12-08-01 but not in 2006-12-07-01. Fixed by reflow branch landing. The disappearing thing is due to rounding and a height less than 1px being set on the rule (depending on font-size, of course). I see it with a non-cairo GTK2 build as well.
(In reply to comment #13) > The disappearing thing is due to rounding and a height less than 1px being set This id fixed as well in Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a2pre) Gecko/20070103 Minefield/3.0a2pre
Dupe of 244932?
Yes, yes it is.
