Inlined JavaScript adds 20K to every HTML file

I was trying to figure out why my documentation site, rendered by Quarto, was taking up around 60MB when rendered to HTML. I found that every .html file (all 273 of them) has the same JavaScript inlined at the bottom of them, adding up to around 20K for each file, or roughly 10% of the total rendered site size.

It seems to be coming from here: https://github.com/quarto-dev/quarto-cli/blob/1dc41fab2e7839c36f55aa0ba21d93c9c9a43ffa/src/resources/formats/html/templates/quarto-html.ejs

It would be nice if this could be refactored and either included in one of the other JS files we already load, or even if it were in its own file, we would only have to have one copy of it in the project, and it would be cacheable.
