Trying to scroll in table data inspector triggers sort change instead of scroll.
Vertical scrollbar: Seems to be about 1px wide, across the whole height of the scrollbar.
Horizontal scrollbar: Seems to be about 1px high, across the whole width of the scrollbar.
The issue is present for a long time, in many previous versions, not sure how far back it goes.
HeidiSQL version and OS

Confirmed.
I'm nearly sure this has to be fixed in https://github.com/JAM-Software/Virtual-TreeView/, not in the HeidiSQL code.
Anyway, the v13 preview does not have that issue: https://www.heidisql.com/download.php#preview-windows-v13
