(Core :: Layout, defect)

Description

[Ho KS]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.7+)

BuildID:    2002010103

The page above has a DIV that has the overflow control on auto. When the page is
first loaded, scrollbar did not appear for the DIV, it is obvious that there are
more content than displayed in the DIV, because of the incomplete sentences.
But if the browser window is resized vertically, the scrollbar appears.
Scrollbar does not appear if window is resized horizontally.


Reproducible: Always
Steps to Reproduce:
1. Open page in URL
2. Check content in the middle of page.
3. Resize window height, or maximize window to make scrollbar appear


Actual Results:  Scrollbar appears only after the window is resized

Expected Results:  Scrollbar should appear when contents exceeds DIV's size.

Verified with 2002012814 and 0.9.7 on Linux.  Resizing it horizontally or
vertically temporarially fixes the problem, however.

Uses 68488 attachment for styling.  The behavior described above should be
evident.

Attachment: Workaround for this problem (ugly hack!)

This bug bit me several times already :( 

I think it's an important one, because the overflow/div combination is the only
(as far as I can tell) way in CSS to create pages that function like the old
frameset/iframe layouts.

The workaround fiddles with the horizontal window size (-1 px, +1px), forcing a
redraw. It's an ugly hack, so if anyone has a better way, please let me know.

My workaround is too enclose the entire body of the div in a single-celled 
table.  The width of the table will not extend past the right margin.  Also an 
ugly hack, but I think it's better than javascript.

This bug is very bad as there is no real satisfactory work around. It makes it
almost impossible to create a page using only divs.

Sometimes luck comes our way... 

I tested all testcases today on RC1 (Xft) on Linux and I can't reproduce the bug
anymore. Seems it magically fixed itself. I noticed some other reflow/layout
bugs being fixed lately, so it seems that somewhere along the line another bug
was fixed that was causing this particular problem. 

Can someone confirm and mark the bug as 'Resolved'?
