184077 - Sub menu hides if cursor touches div with overflow property

Status: RESOLVED DUPLICATE of bug 234788

(Core :: DOM: Events, defect)

Description

[Peter Thomassen]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021207
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021207

When you open a sub menu by touching a menu item and then move your cursor left,
the submenu will hide if you have reached the content div.

The problem is that this div uses the CSS property  overflow: auto;  which you
can easily see in any longer text, such as in
http://www.riemenschneider-gymnasium.de/?uid=efcc5ef93d146ae50c3586a7495f5a13.

There's another nice effect if you do a print preview of this page, but I think
it's the same bug.

Reproducible: Always

Steps to Reproduce:
1. Go to http://www.riemenschneider-gymnasium.de/
2. Open a sub menu
3. Move left

Actual Results:  
The sub menu hides.

Expected Results:  
The sub menu should be shown as IE etc. do.

The same way to get a sub menu is used at http://www.assistance4all.de/ and
http://www.st-josef-grombuehl.de/, and there it works fine using Windows.

On Linux machines, the sub menus at http://www.assistance4all.de/ are not
correct, too, i.e. on some machines the sub menu is shown, and on some machines
it is not.
I have not discovered the difference between these machines yet.

This is a dup of the bug on OS-level widgets triggering mouse out/over events...

Bryner, would you be able to look at this? If not, pass this back to me.
