Since the beginning, not sure what commit (checked with 'guix system
list-generations'), that was:
"Generation 1 September 01 2019 01:15:51"
Probably a fresh Guix System installation from the ISO image from the
website.
Now I run the following commit:
ba7bd6c62ddaab4d5623fb149b47579e13a9e5f5
And the bug is still present

I did nothing special to Icecat, just installed a few add-ons: Umatrix,
Ublock Origin and "Dark Background and Light Text", these add-ons don't
cause any problems on Firefox for example, but removed the ".mozilla"
folder just to be sure, also I remember that displaying numbers hadn't
worked since the beginning, even before I installed the add-ons.  

As for the system, here's my configuration file:
