(Firefox :: Theme, defect)

Description

[Pieter van Vliet]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.1) Gecko/20090715 Firefox/3.5.1 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.1) Gecko/20090715 Firefox/3.5.1 (.NET CLR 3.5.30729)

In the custom theme (e.g. Walnut 1.8.56) I have to following problem.

A jpeg file is displayed. I enlarge the image with <CTRL-mousewheel> or <CTRL-+>, and as soon as the scroll bars show and I enlarge the image further the width of the scroll bars enlarge also. The default theme does not show this problem, but according to feedback I received this is a problem with ALL custom themes, and hence a bug in the common code of Firefox.

Reproducible: Always

Steps to Reproduce:
1. View a jpeg image.
2. Enlarge it with <CTRL-mousewheel) or <CTRL-+> until the scroll bars show.
3. Enlarge it further with <CTRL-mousewheel) or <CTRL-+> which will result in the width of the scroll bars now increasing also.
Actual Results:  
The scroll bars increase in width when an image is enlarged beyond the display window.

Expected Results:  
The scroll bars should not change width when I enlarge the display of an image beyond the display window.
