428694 - Float sometimes pushed down on hi5, especially with slow connection

Status: RESOLVED WORKSFORME

(Core :: Layout, defect)

Description

Attachment: testcase

On this page, it can happen that the image is pushed down the left column.
See screenshots, that someone uploaded.

This is what branch looks like (which is correct):
http://b.imagehost.org/0452/hi5_Fotos_de_Rui.png

And this is trunk when the layout bug happens:

The bug will probably appear especially when the site loads slowly.
This can be simulated with the "clone slowly" bookmarklet:
https://www.squarefree.com/bookmarklets/testbrowsers.html
This makes the bug appear (just use the default settings).

The attached testcase is simplified from the site and it uses the "document.body.offsetHeight" hack to trigger the incremental reflow bug.

The bug doesn't occur on branch, because the site uses display: inline-table, which isn't supported on branch. So this isn't a real regression.
In fact, this is basically the same issue as bug 246669.

If the problem is that the pictures in the hi5 albums are displayed bellow (bellow vertical add, need to scroll down to view them), I can confirm this problem.


If I zoom out to print screen it, however, they will be displayed correctly, so I can't attach an image to illustrate it!

Site changed, AFAIK - well, the content isn't on that URL anymore anyway.
Attached TC renders the same way in Gecko as in other browsers.
