I have a Jekyll blog, where I changed the code highlighter from Rouge (the default) to highlight.js, and it works perfectly.
However, I also want line numbers on my code snippets. Since highlight.js does not provide line numbers by default, I turned to the highlightjs-line-numbers plugin.
I followed the instructions given in the highlightjs-line-numbers usage instructions, and added the relevant lines to my _includes/script.html.
However, for some reason, adding this plugin mysteriously changes the code font to Arial. Here is a link to a blog post which demonstrates this odd side effect.
I have tried to figure this issue out for hours, to no avail. Does anyone know what I am doing wrong, and why this code font change is occurring?
Edit: The current GH Pages is being built from the custom-liquid-tag branch of my repository, and not main.
