Attachment: testcase

This test case contains an iframe obscured by an absolutely positioned div.
Move the mouse over the DIV and see the mouseout fire whenever you move over
the iframe.

Nominating for nsbeta1,topembed since this will cause problems on any page which
uses dhtml menus which overlap iframes.

See discussion in bug 123700; apparently the fact that the iframe is a native
window makes us get an OS-level mouseout event when we move over an iframe....

I'm curious as to where this bug is going?  We see the same issues and have had
to implement functionality changes to work around it.

This bug does appear to be the same as bug 125386.  It seems to be effecting any
scrollable element.

Comment 9

[Joakim Recht]

I worked around the problem by doing something like

li-object.onmouseout = function (e) { 
  var tmp = e.originalTarget.nodeName;
  
  // js-code to hide div
}

I have no idea why that makes a difference, tmp is never used again...

I tried to use the workaround Joakim Recht described, but without any results. I
find it strange that this bug is over a year old, and still no progress is in
sight; I think that the moz developers should redirect their attention from
creating new features to fixing bugs!

This works fine now that 125386 has been fixed, can anyone verify? Using trunk
build 20050224.

Comment 18

[Dimitrios]

with trunk FF 20050225, attached testcase works as expected. Behaviour on
testcase of comment 16 has changed but is still not correct.

Please file a new bug with a new reduced testcase and explanation if there are
remaining issues.
