Why was the pr before this supersede?

[wendigo]

@nadavtzaysler it's a simpler implementation

[nadavtzaysler]

@wendigo It's a simple change in the css file, could've been made in the same pr

Also woof2 files are considered better to use in web apps so i believe the implementation before is more ideal

[nadavtzaysler]

@wendigo @mosabua I still dont understand why is this simple remove of a few lines in the fonts.css file is requiring a new pr, basically until 5 minutes ago it was just a worse copy of the original pr that will take about 3 to 4 more days to merge while the original was ready

[wendigo]

@nadavtzaysler this PR isn't a copy, I've made it from scratch addressing the linked issue

[mosabua]

I dont mind which PR is merged - whichever is better. I think we should just add a co authored by line in the commit message so the changes are attributed to both @nadavtzaysler and @wendigo

[wendigo]

Since CLA is not signed I can't add authorship and as said these are two separate PRs addressing the same issue with two different and distinct implementations @mosabua
