327536 - inc? Page renders differently each time, a right floating div will be misplaced below the left div.

Status: RESOLVED INVALID

(Core :: Layout, defect)

Description

[Dom]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.0.1) Gecko/20060111 Firefox/1.5.0.1

Firefox seems to render this page differently sometimes for what seems like no reason. In IE, Safari and Opera the page will load correctly, with a div on the left and a div on the right - side by side. However in Firefox this is still the case, but not everytime! When you first load the page, it may load correctly but within three more refreshes the right div will misbehave and will misbehave and drop below the left-floated div. (still side by side, but just underneath).

Nothing is changing each time I refresh, however Firefox renders it differently.

Reproducible: Sometimes

Steps to Reproduce:
1. Load http://skatebasingstoke.com/index.php
2. If the page loads correctly, refresh until it misbehaves.

Actual Results:  
The right floated div misbehaves sometimes.

Expected Results:  
The right floated div should be placed next to the left, every time.

Confirmed on FIrefox 1.5.0.1 on Windows XP

This is still the case with 

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9a1) Gecko/20060316 Firefox/1.6a1

But it only happened once in 30+ reloads.

Happens on a yesterdays trunk build as well.

Confirmed on Firefox 1.5.0.1 on Windows XP; similar symptoms may be found at http://www.videogameszone.de/ - every 30th or so refresh renders the middle column positioned in the bottom left under the navigation instead of where it belongs. Using the Web Developer Extension, you can disable CSS, re-enable it and the middle column will always show up exactly where it is meant to be. A couple of clicks/reloads later, the rendering bug will strike again, though. This also applies to the URL of the original poster.

No confirmations with 1.5 or 2.0 builds are needed, they have an older version of Gecko (the layout engine). I was able to reproduce this bug with the latest build of Gecko about a month ago, the only reason this bug is in unconfirmed state is that I wasn't sure if it's a dupe of some known bug.

I guess a minimal testcase showing the bug would be welcome.

The authors of the URL I submitted seem to have changed something - I cannot reproduce the bug any more. The only thing I have noticed that seems to have changed is the dtd - both the skatebasingstoke.com and the "old" videogameszone.de used to use loose.dtd; the latter has now changed to strict.dtd. So I guess it might have something to do with this.

I have to correct myself - the rendering bug is still there, it's only a little bit less frequent than I expected - about 5 in 100 page reloads show the error.

Try <div style="float:right">INSERT GOOGLE MAP CODE HERE</div> and see what happens in firefox 3 versus firefox 2 and Internet Explorer 7

I think you bwoke the internet
