A menupopup with position="after_end" pops up in the correct position, but when
it is resized while it is up, it shifts to the default "after_start" position.

This is a concern for popups that are much wider than the menulist or vice versa
(with sizetopopup="false"), as the popup unnecessarily jumps horizontally.

Reproducible: Always

Steps to Reproduce:
In sample xul:
1. Click drop down button:  
   popup is below text field, aligned with left edge
2. Click 'more' button: 
   popup resized, but now is below text field, aligned with *RIGHT* edge

Actual Results:  
Popup shifted position from aligning with left edge to aligning with right edge.

Expected Results:  
Alignment should stay the same as directed by position attribute.
