ui: Fix scrollbar mouse down handler (#35131)

Finn Evers created 4 months ago

Follow-up to https://github.com/zed-industries/zed/pull/35121 - in the
process of adding the check for the left mouse button to the guard
(which was practically already there before, just not in the mouse-down
listener), I accidentally removed the negation for the bounds check.
This PR fixes this.

Release Notes:

- N/A
