191155 - Opening and closing print preview or text zooming causes major layout horkage with dynamic content

Status: RESOLVED INVALID

(Core :: Layout, defect, P2)

Description

[Eric A. Meyer (dead account)]

The test URL is a Netscape internal URL of a site, so at the moment only those
able to get behind the Netscape firewall can see it.  The site in question will
be public in the very near future.

Steps to reproduce:
1. Go to URL.
2. Run the mouse over the horizontal bar of links near the top of the document;
notice the menus opening and closing.  (They're driven by a lightweight CSS/JS
approach.)
3. Open Print Preview, then close Print Preview.
3b. Alternatively, use Text Zoom to change the text size, and either return it
100% or don't, it doesn't matter.
4. Run the mouse over the horizontal bar of links near the top of the document.
 Notice the horkage.  It appears the containing element of the menus is being
vertically expanded to contain them, and then some, despite the CSS that should
prevent that.

Expected results:
The menus would operate as they did before open/closing print preview or text
zooming.

Actual results:
The menus' container expands to "shrink-wrap" the menus, which is not good.

Well.. jkeiser is the only person doing active layout work that could access
this, so.... ;)

I could be wrong, but since Devedge had a major design change recently, this
might be related to the new code.  

I'm not seeing the problem described at the devedge site in 1.3.

If devedge is the correct site, the reporter should see if this is fixed.

This problem does not exhibit itself on devedge using 2003052309 nightly.
Please either post a minimized testcase or mark this WFM.

I'm unable to reproduce this problem.  I've tested this with build 2003120109.  
I experienced no "horkage".  I think more detail is needed in order to 
reproduce this problem.  I attempted to go to the site listed above but it was 
unavailable.  Instead, I used www.entrust.com, which contains some dynamic 
content.  I proceeded to zoom in our over 20 times with no change in layout in 
either the preview window (which I assume that's what you mean) or the main.  
Opening and closing print preview over 20 times did also not result in any 
horkage.
