Greasemonkey RES

I miss Reddit Enhancement Suite so much and when I found a maintained reimplementation of RES in Greasemonkey I got all excited... Except I cannot seem to make the darn thing work in Qutebrowser...

Looked kinda like it was a ti ing thing with the DOM, but changing the script to run at document-end didnt help either.

Does anyone have this running, or have any ideas of things I could try?
