If your goal was to be helpful, you should really be more specific than just "linux". It works fine on Firefox / Ubuntu Xenial for me.

In any event, I'd suspect it was more likely for the problem to be in the browser rather than than the kernel...

If your goal is to be helpful a little less pedantry would be in order.

Firefox / Ubuntu Bionic, probably related to font choice or font-rendering library.
