I had a couple of issues, including the following:
* Cannot drag regular text, which is not a link.
* If I drag the scrollbar, and move the mouse away, the scrolling stops.
* Some text selection anomalies.

I found an alternative, though, which works well for me:

EDIT: looks like it's fixed now. Thanks!
