You can totally get rid of the blue hover.

"While we try to avoid breaking customizations"

I've looked at the page source, and can find no evidence to support this statement.

"Only issue is that it won't work for the notifications menu if it hasn't yet been clicked (its content is only loaded on click, it seems)."

Sounds very similar to the "If you hover over the notification icon before the page has completed loading, it never loads" bug which was still happening yesterday.

edit: and it's still happening now if you click the notification icon before the page has completed loading.

edit: surprisingly, my fix for the scrolling issue still works. Unsurprisingly, Wikia still haven't fixed the scrolling issue in the notifications.
