Hi there. Sorry about this, I didn't realize it was 'hijacking scrolling'. I tried a possible fix. Could you let me know if you still see the problem? Thanks.
Scrolling, highlight/selection colour, fixed-position elements (I've ended up nuking your site's header entirely), autoplay audio/video, mouse action, click actions (either opening left-click in new tab, or center click in same tab), etc.
All violate the principle of least surprise/astonishment. Quite annoying.
You can have your horrible purple/blue... I'll take people hijacking those abominations any day of the week.
Otherwise, that's a good list. :)
White text on a blue field works well for me.
