What is the CSS selector that makes this giant space between the last rem and the references?

I tried resetting my KB and also toggling on/off all the CSS I could find. But I can’t figure out what is making such a large space between the last rem and the references. (It is not empty rems. When I press delete or delete-forward, there is nothing.)


You can remove it with this code…

.rem-hierarchy-bottom {
	height: 20px; /* i think 20 is beautiful.. */
}

That’s it! Works perfectly! Thanks so much!
