Andrew. Thank you for your report.
The reason for this code instruction (i.e. "unset") is to avoid intervention and consequent unwanted effects of other stylesheets.
Do you think that a context-menu or a greasemonkey-menu form of this Greasemonkey script be a good solution for you?
I also suggest to use 4get, LibreX, LibreY, Lieu, Metastem, SearxNG, Spot or YaCy instead. There are many quality alternatives.
Merry Christmas, and a Happy New Year!
