Thanks for another great userscript!

I just noticed this minor issue: (using GCN 1.0.3 in FF48 x64 in win10 with GM 3.8)
there's a slight truncation in the icons' left side.

Here is a (resized) screenshot where I highlight the truncation (it's a few pixels) :
-using a clean FF profile with only (GM and) GCN-

And here is when the truncation doesn't occur:

It occurs in e,g,
https://github.com/
https://github.com/Mottie/GitHub-userscripts

It doesn't occur:
https://github.com/greasemonkey
https://github.com/greasemonkey/greasemonkey/wiki

Having unread notifications (i.e. having the dot on the bell icon) or not, doesn't make a difference.,
