Bug Description

I am not using overlay scrollbar, so just normal scrollbars.

Steps to reproduce the issue:

- Open a program with large scrollable content, where handle is small (for example, a long pdf in evince, or even the sound volume scrollbar of indicater-sound - It doesn't happen with Firefox)
- Take the scrollbar (left mouse press on scrollbar handle)
- **Very slowly** start moving the mouse for a second or two
- Move the mouse normally

Expected behavior: The scrollbar handle moves with the mouse with the same speed

Observed behavior: The scrollbar handle moves with greatly reduced speed compared to the movement of the mouse
