Status: VERIFIED WORKSFORME

(Core :: DOM: Events, defect)

[[e-mail] (gone - use [e-mail] instead)]

URL: http://www.msnbc.com

Summary: Mouseover navigation menus disappear 1/2 way 
Build ID: 2002-01-07-03, Windows 2000 **Commercial** build.

This only affects the commercial build, but that is because their sniffer code
doesn't correctly detect Moz (by using the .family property).

Steps to Reproduce:

1.  Load http://www.msnbc.com
2.  Mouseover 'Technology'.
3.  Somewhere 1/2 way through the menu (traversing down it), the DHTML menu will
simply disappear.

Expected Results:

Menu appears, and it open until you mouse away from it.

Actual Results:

The dynamic menu disappears near 1/2 way through traversing it.

'Technology' isn't a special category, the rest of the categories behave the
same way also.

Seems like the image on the bottom of the page is the problem, when you mose
over that in a menu (i.e. when the image is behind the menu) the menu goes away.
Over to DOM Events.

Any investigation on what's special about the image, or something close to the
image would be greatly appreciated.

I see this on my linux build, too, marking OS/Plat -> All.

It appears that the problem may be related to the fact that the img which causes
the submenu to close has a usemap.

Their menu code http://msnbc.com/tools/nm/nmjs02.js uses Event.target for
Mozilla and window.event.srcElement for IE. target can be any Node not just an
Element for us. Did our behavior with respect to setting target on image maps
change since 094?

Note that this problem does not appear in Mozilla 0.9.4.2 with a NS6 ua string
but does appear in Mozilla 2002-01-11-03/win2k with a NS6 ua string.

Adding nsbeta1 keyword to all regressions so they *get some love* and attention.

This also occurs on

If we ship another milestone with this bug we should be ashamed...

This bug seems to also cause some major problems on the official Olympics 
website - bug 120934.
