89326 - overlapping layout

Status: RESOLVED DUPLICATE of bug 82946

(Core :: Layout, defect)

Description

[Jacob Kjome]

using build 2001070411 on Win2k (SP2)

Steps to reproduce:
1. load http://www.wired.com/news/technology/0,1282,44800,00.html
2. Look at the red "TECHNOLOGY" and red horizontal line.

The other regular text seems to be overlapping the red text and red horizontal
line.  I have no time at the moment to investigate, but I suspect it may be a
floater bug.  Will look more into it tomorrow.

hmmm.... this is strange stuff.

Using build 2001070609 on Win2k (SP2)

The first time I loaded th page, the content that overlapped wasn't doing so.  
However, on a normal reload it overlapped.  Then, on a shift+reload, it layed 
out just fine again.

Could this be related to bug 79983?  Not sure.  I'll see if I can find the 
offending html.

Attachment: image showing overlapping - hard to reproduce which is why I made the image

The testcase I just posted does not always produce the overlapping behavior, 
but does show that a first-time-load/shift+reload act differently than a 
regular reload.

1. Load the tescase:  http://bugzilla.mozilla.org/showattachment.cgi?
attach_id=41527
2. click "reload"
3. notice the change in placement of some of the elements on the page
4. click shift+reload (notice the change in placement again)
5. click reload (notice the change in placement again)
6. etc...

Every once in a while I got the behavior shown in the jpeg image that I 
attached which shows the content totally overlapping the large image on the 
page.  This was hard to reproduce.  I got the behavior exactly twice in about a 
20 minute period of testing.  The second time I got it, I figured I'd better 
get an image of it to prove I'm not crazy.

Anyway, This does not seem like a floater bug, since no image has an align 
attribute and they aren't using stylesheets.  

I think the component might actually be HTML Tables, but I'm leaving it on 
Layout for now, since I don't have a clue as to what is causing this.

BTW, I HTML Tidy'd my reduced case and I did the same to the main source.  When 
I tested out the tidy'd version of the main source, I got the same behavior 
reported at the URL so as bad as the html is on that page, even the Tidy 
corrected version displays the overlapping behavior.

I can confirm in the original testcase but not the reduced testcase. At any rate
this is a dup of 82946
