User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a) Gecko/20040517 Firefox/0.8.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a) Gecko/20040517 Firefox/0.8.0+

When a page contains one or more iframes, and the iframes have a vertical scroll
bar, dragging the scroolbar all the way down with the mouse while holding the
left mousebutton pressed, then moving the mouse left or right away from the
scrollbar keeps the scrollbar scrolling even though you did not select it
anymore with the mouse.

Reproducible: Always
Steps to Reproduce:
This one is very picky and requires some precision mouse movement, i'll try to
be as accurate as possible:

0. Open up a webpage containing an iframe (the one i'm typing in right now on
the bugzilla server
(http://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox&format=guided) will
do quite well
1. Click on the vertical scrollbar of the iframe, hold the left mouse button and
drag it all the way down. Do not release the mousebutton yet!
2. While keeping your mousebutton down, move your mouse left into the iframe (or
right outside of it), either way not hovering over the scrollbar anymore. Now
release the mouse button.
3. Now with the mousebutton not pressed, hover over the scrollbar you just
dragged down. You will see that the scrollbar follows your mouse even though you
are not dragging it!
Actual Results:  
The scrollbar follows the mouse even though the left mousebutton is not pressed.

Expected Results:  
The scrollbar should not follow your mouse when the left mousebutton is not pressed.

Does not happen in: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a)
Gecko/20040510

But I can confirm in: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a)
Gecko/20040517 Firefox/0.8.0+

Looks like it's Firefox specific (which is rather surprising).

It seems to be fixed in:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a2) Gecko/20040526
Firefox/0.8.0+

Or at least, I can't reproduce it anymore on the same site i found the bug on...
