From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; 0.8.1) Gecko/20010323
BuildID: 20010323
If two IFRAMEs are partially overlapped, the display will be incorrect. The
IFRAME with lower order will display instead of the IFRAME with higher order in
the overlapped region. Although the display is incorrect, the EVENT system is
correct. in the overlapped region, the IFRAME with higher order will receive
EVENT, and the orther IFRAME will not receive EVENT, even if the display is
incorrect.
Reproducible: Always
Steps to Reproduce:
I write a typical example, it is in the 'Additional Information'
Actual Results: Display is incorrect!
Expected Results: In the overlapped region, the IFRAME with higher order must
be displayed.
I wrote an example below:
Open index.htm and move the cursor to the overlapped region, You will find that
the EVENT system is correct, but the display is incorrect!!
.......index.htm.........
<HTML>
<BODY>
<IFRAME
STYLE="position:absolute;top:10px;left:10px;width:100px;height:100px"
SRC="a.htm"></IFRAME>
<IFRAME
STYLE="position:absolute;top:60px;left:60px;width:100px;height:100px"
SRC="b.htm"></IFRAME>
</BODY>
</HTML>
........a.htm...........
<HTML>
<BODY BGCOLOR="red" onMouseMove="parent.status='red'">
</BODY>
</HTML>
.............b.htm............
<HTML>
<BODY BGCOLOR="blue" onMouseMove="parent.status='blue'">
</BODY>
</HTML>

The fix for bug 43410 should address this problem - the iframes will now clip
each other correctly, and not paint overlapped.

In the example code attached, there is no z-index setting. So both z-indices
are auto and the iframes should just be z-ordered based on order in document,
the second on top. This is exactly what happens. The blue frame is on top, the
blue frame gets the mousemove events.
This bug is invalid as stated.
