Bug not seen in 1.9.0 branch or 1.8 branch

Saw it first on vertical scrollbar, but also could it produce on horizontal scrollbar.

Steps to repeat:
1. Try scrolling down by clicking on top arrow and dragging it down: doesn't work
2. Then click on slider and drag it down: works, but when you release it, it scrolls automatically up.
3. Stop movement by clicking on up or down arrow of the scrollbar, doesn't matter which.

better Steps to repeat:
1. drag sliders somewhere in the middle of the scrollbars.
2. click an arrow of a scrollbar, drag it into the scrollbar area before releasing it. The slider starts scrolling towards the arrow.

Old bugs may be related:
Bug 157123 – Browser scrollbars continue scrolling after I release mouse button
Bug 420944 – If top scroll bar arrow held too long, page will automatically scroll to top and not scroll down 
Bug 442130 – scroll bar works incorrently

Relevance of the bug:

Annoying.

Found it because under some lighting conditions (bright sun) the exact position of the mousepointer isn't very visible on my display, so I by chance I tried to drag the arrow instead dragging the slider.

People seeing this bug don't see how it comes up or can be stopped, most simple workaround is reload.
