Steps to replicate the issue:
- Visit any page with Vector-2022 skin on a desktop computer
- Scroll down.
- Click (keep mouse down) on the 10th text line from the visible top. Even worth: on the 2nd text line from the visible top.
- Move your cursor slowly toward the top: you’re highlighting the text.
What happens?:
When your cursor arrives at about 60px from the visible top (viewport eventually shifted by sticky header), the page starts to automatically scroll up.
Even worth case: you’re already in the “60px zone”, so the page very quickly scrolls up.
What should have happened instead?:
The scroll should only happen when the cursor leaves the visible part (viewport, or sticky header when there is one).

Tested with both Firefox and Chromium on Debian.
