When you dynamicly create a progressmeter, set it to hidden and then show it again, the animation stops and you won't be able to start it again. I think tried to debug the progressmeter.xml binding and it appears the settimeout loop stops working when toggling. 

Reproducible: Always

Steps to Reproduce:
1. Dynamicly add Progressmeter with createElement and appendChild
2. hidden = true
3.hidden = false;
Actual Results:  
Voila, animation stops

Expected Results:  
Animation should show up again, just like in 1.9.0

I tried several builds, the problem doesnt appear on 1.9.0 but does appear on 1.9.1 and 1.9.2 aplha2.

Attachment: Testcase1

This window.xul illustrated the problem i'm having with undetermined progressmeters in xulrunner  1.9.1 and 1.9.2.

UPDATE: Testcase1 is working when calling setAttribute() so more factors are involled. I'll try to create an updated testcase as soon as i'm able to determine what exactly makes the progressmeter fail in our framework.

Can't reproduce (anymore). Haven't been able to make a testcase.
