[v4] pseudo element content is applied on hover when it shouldn't

In v3 this doesn't have after:content when hovered
In v4 this does have after:content when hovered

And this element doesn't even have something like after:content-[''] applied at all, so after pseudo element isn't expected to be visible at all.
