How to update "Fade Out" effect on recently visited Topic row?

Thanks so much, Sam!

I’ve updated my CSS with the following:

body.category-XXX-bugs .highlighted {
    background-color: rgba(255,255,255,0.7)!important;
}

But this is the effect I get, rather than the nice fade-out transition that’s there normally. Do you have any suggestions on how to maintain the effect along with updating the color?
