This is not a regression, but long standing problem.

Steps to Reproduce:
1. Start Minefield with new profile
2. Open Web page (long enough to scroll, e.g., https://developer.mozilla.org/En/Code_snippets/Tabbed_browser) 
3. Selection start by mouse down and hold the mouse
4. Drag selection downward or upward

Actual Results:
  Drag selection upward   : Scroll speed is slightly slow.

Expected Results:
At least, same speed as downward selection
