the provided test page has two DIV tags absolutely positioned inside an IFRAME 
area, both DIV tags have onmouseover/onmouseout events set up to change 
background color.

the mouseover event is fired correctly, while the mouseout event is fired only 
when the mouse moves into the other DIV tag or out off the IFRAME border.


Reproducible: Always
Steps to Reproduce:
1. load the test page
2. mouseover one DIV, background color changes
3. mouseout to IFRAME area (grey), nothing happens (no mouseout event fired)
4. mouseover another DIV or mouseout the IFRAME area, first DIV background 
color restores (mouseout event fires now)

I see this too.

The mouseover event triggers *always* when entering a DIV (blue square).
The mouseout event triggers *only* when leaving the iframe (grey area), either
by moving over the DIVs or out of the iframe area.

I think bug #262194 is a duplicate of this one.

Anybody with enough "access rights", could you please double check and if
confirmed, mark the other bug as duplicate. Thanks.

Bug #155276 does the same with the IMG element but is (currently) lacking a
testcase.

Do we have an update on this? 

This bug seems to be getting more attention from our users.

Another test case can be seen at http://www.milonic.com/bugreports/mozbug2.php
