Anybody else having trouble with the sample article in HTML at pretextbook.org?
Seems to be Firefox. Local and Chrome work fine. Maybe just the sample article
- the sample book seems fine (except for math in Exercise 5.10.1). Hangs up
while doing something with a message "Read cdn.jsdelivr.net". This could be
MathJax, Mermaid, DoeNet, or a bunch of other things. Not having much luck with
the Inspector (etc.) since it is unresponsive.
Any insights?

Yes, MathJax related.
The page is ending up with both:
<script src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-chtml.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.7/MathJax.js?config=TeX-MML-AM_CHTML" type="text/javascript"></script>
FF is finding 2.7.7
Chrome is finding 3
Finding 2.7.7 breaks all the code that expects to work with 3:
Uncaught TypeError: can't access property "components", MathJax._ is undefined
We've had similar issues before with FF finding a different version given the same code that tries to load both.
The real fix is to not try to load MathJax 2.7.7 and 3 at the same time. Not sure off the top of my head what might be loading the different versions.

Thsanks, Andrew! I think that is from some STACK stuff, that maybe I left in by
mistake. I'll get it sorted in the AM.
(I'd noticed other less-severe MJ problems lately, too, so hopefully those go away.)

Thanks again, Andrew. I shoulda been able to sort that one out. ;-)
I have disabled loading MathJax 2 when a STACK question is present. So now
STACK questions will not render properly in HTML. So I have (again)
(temporarily) commented-out the one test question in the sample article.
A lot of other math was rendering fine, so I thought this was OK, I guess. But
commutative diagrams were not rendering, and our custom setup for knowlds in
display math were not working. And that was just locally - hosted on a server
it was much worse.
@Georg - we have to get this straightened out before we can make much progress
on anything else. You can assume MathJax 3 is loaded and available, and work
with that from within the STACK JS. And if it was done in a way that MathJax 4
was happy that would earn bonus points.
@Oscar - we might need a point-realease of the CLI? Except my website update
just now is still not right, so maybe I have more work to do.

Based on some Drop-In discussion, I tried a few more things. Reviewed all the
HTML changes, going back months. Tried a local web server, so I could use "git
bisect", but it doesn't show the problem. Rebuilt a cleaner version for the
website (no stray old files).
It seems to only be the sample article. And only on Firefox. And it hangs so
bad, I can't even get the Inspector up. Only last thing I can think of is that
pretextbook.org recently moved and maybe the server is configured differently?
Anyway, I give up.
@Oscar - let's go ahead and do a CLI point upgrade - for several reasons, but
partly for all the messing around with display math. Thanks.
