I rarely see trivial suggested edits in the Sandbox, it's occasionally difficult to decide to keep them; because the person is genuinely testing something or delete them so they never hit the queue again.
@rene thanks. I don't think it will gain much traction, but at least it feels more at home on Chess Meta. So please migrate @Aibobot / @JourneymanGeek.
FYI, the maintainer of Highlight.js stated that while they won't be monitoring the meta sites for issue reports, they prefer that they first be posted on a meta site so that the community can vet them and determine if they're actual issues, rather than simply directing all issues straight to the issue tracker as was done with Prettify.
