User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6

The onmouseout handler is not being called 50% of the time. Appears to be a race
condition. 

The bug has two requisite conditions: 
1) text position is changed (i.e. changing text *color* does not reproduce bug)
2) text position is changed via setTimeout()

No known workaround. 

Reproducible: Always

Steps to Reproduce:
1. browse to specified web page
2. move the mouse over link "b"
3. move the mouse out from link "b"
(repeat 2 & 3 twice to reproduce)

Actual Results:  
Nothing happens. The mouseout event handler was not called. 

Expected Results:  
Text moves back to original position.

Please test with a newer build before filing rendering engine bugs. Firefox
1.0.6 is based on gecko 1.7 that is over one year old.
