256879 - main window scrollbar causes absolute media content position to indent

Status: RESOLVED DUPLICATE of bug 72540

(Core :: Layout, defect)

Description

[Shane Mann]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040614 Firefox/0.8
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040614 Firefox/0.8

I've verified this in Netscape 7.1 and Firefox 0.9.

A centered block of html with whitespace margins has its upper-left corner at a
certain (x,y) position depending on how wide the html block is. This block doesn't
go off the bottom of the screen so no scrollbar is required nor rendered.
However, when an html block with the exact same width but greater height is
loaded and the scrollbar is rendered the given upper-left corner coordinates of
that html block are changed. I checked IE and it has no similar problem.

Perhaps one wouldn't consider this a bug since its mostly aesthetic. In my
personal opinion this behaviour is a problem and should be fixed.

Reproducible: Always
Steps to Reproduce:
1. Load a centered block of html with a certain width and a height that doesn't
require a scrollbar to view all of the content.
2. Load a second block of html with the exact same width as the first but a
height that requires a scrollbar to view the rest of the content.
3. FLip back and forth between the two. You'll notice an x,y difference of the
upper-left corner of each block of html.



Expected Results:  
Instead of changing the given x,y position of the upper-left corner of the two
html blocks it should remain the same.

Note that when IE doesn't need a scrollbar it still draws it... That's the only
difference between the IE behavior and the Mozilla one, in fact.
