263639 - Select text breaks scrollbar

Status: RESOLVED DUPLICATE of bug 263632

(Firefox :: General, defect)

Description

[Adonikam Virgo]

User-Agent:       Mozilla/5.0 (Windows; U; Win98; rv:1.7.3) Gecko/20040913 Firefox/0.10.1

In the page at http://www.csszengarden.com/, selecting all of the text on the
page (which IE can't do properly!) causes the scroll bar to stop working. You
cannot scroll with either the bar or the arrows - when you click it, the
selection disappears, and then an alternative selection is made starting from
the point on the page you clicked the bar.
You can however scroll with the keyboard arrow keys or the scrollwheel on the
mouse with no problems.

I reproduced this with the default css theme, beccah and medioevo. On teatime
and centerfold, where the menus are to the left, the functionality remains.
Others I could not even select more than one paragraph of.

This seems to be a special case where many divs are used - this gives the select
algorithm a more complicated task. The problem seems to be that it receives the
click as a request to perform a select operation rather than a request to the
scroll bar widget, but I'm no expert.

I only once couldn't reproduce this problem, but didn't remember how.

Reproducible: Sometimes
Steps to Reproduce:
1. Load http://www.csszengarden.com.
2. Select text on the page from anywhere on the left to "Translations" on the right.
3. Click and drag the mouse on the scroll bar.

Actual Results:  
A new selection is performed.

Expected Results:  
The page scrolls and the selection remains.
