User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050605 Firefox/1.0+

Drop down boxes do not remain when they appear above but do when they appear below.

Reproducible: Always

Steps to Reproduce:
1. Go to a site with drop down boxes like the URL linked in bug report.
2. Single click on the down arrow to bring up the menu.
3. Try when the drop down box is near the top.
4. Try when the drop down box is near the bottom.

Actual Results:  
When the menu displays above the drop down box it disappears as soon as it
appears. But when the menu displays below the drop down box it remains as expected.


This happens on other sites as well. This first appeared with the 20050602 trunk
builds.

Works with 2005-06-01 build, fails with 2005-06-02 build. I think a regression
from fixing bug 290428.

Clicking on the down arrow works for me, though.
But when clicking on the text in the combobox, the popup immediately closes when
the popup opens above, when I release my mouse button. 
When the popup opens below, everything works all right, the popup stays open,
I've released my mouse button.

most likely regressor bug 290428

This does not occur when clicking on the arrow-down button to drop down the box.
Only when clicking in the box itself (the text in it) I get these problems.

No, it'll only stay up if it contains a scrollbar and you press on the arrow, if
not, it'll collapse when you click on the arrow.

try the "Version" dropdown on this page

Note that this occurs on Mac as well, hardware should be changed to "All".

That'll do. Thanks, I was just about to get to this, honest :-)

This is a must-have for 1.8b3, it's a serious UI regression

Actually it should be

if ((pt.y >= bounds.y) && (pt.y < bounds.YMost())) {

I'll check this in.
