(Core :: DOM: Events, defect)

Description

[Timothy C. Quinn]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040206 Firefox/0.8
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040206 Firefox/0.8

When iFrame exists on page whether hidden or visible, it will cause popup menu's
to fire a mouseout event even though the z-index of the iFrame or containing
element has a lower z-index than the menu.

IE 5.5+ works correctly.

Reproducible: Always
Steps to Reproduce:
1. Add and iFrame in the range of a popup menu.
2. Set iFrame to lower z-index than popup menu.
2. Have popup menu show and when mouse goes over iFrame.
3. Mouseout will fire on menu when over the iFrame.

Actual Results:  
mouseout event fires for menu

Expected Results:  
mouseout should not fire since mouse is still over menu which is at the top of
the z-index of layers

Attachment: Simplified (sort of) Test Case

This test case will work in both Mozilla and IE. It probably could be
simplified a little further.
