Using the well-known Sons of Suckerfish Dropdowns
(http://www.htmldog.com/articles/suckerfish/dropdowns/) CSS technique, hovering
over a menu item creates a dropdown menu that can be parent to a second-order
dropdown. In Mozilla 1.7.5 and Firefox 1.0 (and 1.0.1) on the Mac only, mousing
over the parent of the second-order dropdown causes the dropdown box to appear,
but also causes miscellanous lines of text from below the original dropdown to
overwrite it. This problem only occurs when some of the menu items above the
triggering item wrap to two or more lines. The trigger itself can be one or more
lines long.

This problem does not occur in PC Mozilla/Firefox, or in PC IE6, or in Mac Safari.

Reproducible: Always

Steps to Reproduce:
1. Please see http://pighog.com/suckerfish/
2. Mouse down to the "Trigger" menu item in the "TEST MENU" dropdown.
3.

Actual Results:  
Lines of text in page elements below the dropdown menu are visible through (or
overwrite) the dropdown menu

Expected Results:  
The dropdown menu should have remained opaque, masking the text below

To Mac widget, but is this an issue in a current trunk build?

Bug is still there in Mozilla 1.8b2 (build 2005022610)

I can repro this in FF, but not Camino. It happens when you hit the menu item
with a submenu (I guess that somehow causes the rest of the text to redraw).

I can reproduce this with Firefox 1.0.5. I can't reproduce this with Deer Park
Alpha 2. I can't reproduce it with the earliest nightly still available on our
ftp site (2005.6.29).

Marking WFM as it works on trunk and its probably not going to get tracked down
for the branch. Even if it did get tracked down, enough changes have been made
that its not worth the potential bustage on the branch.
