User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.3a1pre) Gecko/20090905 Minefield/3.7a1pre

When an element focus moves from one to the other (e.g. display tooltip, hide/show an element), framework send "mouse out" event to previous element if the elements on a xul:panel element.

This affects all tooltiptext on xul:panel element.

Reproducible: Always

Steps to Reproduce:
1. create a xul:panel and put an element with tooltiptext
2. Launch firefox and hover mouse to the element

Actual Results:  
It appear tooltip text few second later, and immediately disappear because displaying tooltip send mouseout event to the element

Expected Results:  
It shouldn't send mouseout event to the original element.

I attached sample XUL code which added small text on statusbar. click "Click here" text to open xul:panel.

Statusbar tooltip works fine. However, tooltip on panel doesn't work.

Bug 513684 hasn't been checked in yet on mozilla-central ...  My apologies if I jumped the gun a bit on marking it as a duplicate.

Bug 513684 was checked in a couple days ago.  Does this still appear on trunk?

It seems working appropriately on 

firefox-3.7a1pre.en-US.mac.dmg	28-Sep-2009 06:28 	 23M

Is this patch also going to apply Fx 3.6 branch?

Bug 513684 was landed on 1.9.2 this morning.  As I said in comment 5, if I understand the bug correctly it is fixed by that patch.  Per comments 5 and 10, changing to duplicate for recordkeeping.
