[SOLVED] Thanks button bug

Hello,
I just noticed a bug that happens to the link next to the "thanks" button on translations which have 0 thanks: https://imgur.com/ZmwZatL
The target of that link is also used as its text.
Clicking on it opens the pop-up with the list of the people who said thanks, but of course empty, while the link itself should not be there at all.

EDIT: I realized it's because of the following CSS property, which does exactly that:
a[href]:empty::before {
 content: attr(href);
}
