234578 - clear: right doesn't work with float: right and vice versa

Status: RESOLVED FIXED

(Core :: Layout: Floats, defect)

Taken from page:

The two colored boxes above are left and right floated boxes. Left comes first
in the source, right second, and both are followed by a flowed header ("The
Setup") that has 'clear: right' applied to it. The floats have a fixed pixel
width. That's basically all there is to it. The body is margined a bit, and the
main header is absolute, so it is not involved with this demo in any important way.

So you're asking "what's the big deal?". Well, when opposing floats like this
cannot both fit side by side in a container, the second one is forced below the
first. In this case the green right float would go below the red left float (but
still remain floated to the right). Since the header is cleared for right
floats, it should appear below the right float.
The Bug

In Mozilla that does not happen. Instead, if the screen is narrowed enough to
cause a float wrap, the header (and the following flowed elements) begin up
alongside the left float! In fact, the content is broken into two sections. 

Reproducible: Always
Steps to Reproduce:
1. Load page
2. Resize browser window
3.

Actual Results:  
Text flowed in wrong place

Expected Results:  
A different rendering of text placement

Attachment: simplified test case

Simplified test case - width's/border's are only present to make seeing the bug
easier - the bug occurs without them as well. Just make the window narrower and
watch the result.

I think this was fixed by fixing bug 148994.

The testcase shows the bug in:
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8a2) Gecko/2004-06-07
Firefox/0.8.0+
The testcase doesn't show the bug in:
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8a2) Gecko/2004-06-09
Firefox/0.8.0+

See also the story in the url's testcase at the bottom. (At the "Correction:")
