In case anyone is interested, I recently submitted this PR to support math in horizontal Parsons problems. It appears to be working, but I am sure more kinks must be hammered out.
This might be a good way to construct formulas and equations (term-by-term) if multiple correct orderings can be supported (for addition/multiplication).

I am trying to use this for a PROTEUS problem, and the math isn't rendering.
Here is my output in HTML:
This is the source that produced it:
<exercise label="APEX-PROTEUS-lhosptial-2-v1" component="proteus" language="natural">
<statement>
<p>
Place the functions below in order from left to right according to the following rule:
<m>f(x)</m> is to the left of <m>g(x)</m> if <m>\lim_{x\to\infty}\frac{f(x)}{g(x)}=0</m>.
</p>
</statement>
<blocks layout="horizontal" randomize="yes">
<block order="5"><m>\sin(x)</m></block>
<block order="2"><m>\ln(x)</m></block>
<block order="6"><m>\sqrt{x}</m></block>

<block order="1"><m>e^x</m></block>

Am I getting something wrong? I think my source aligns with the example in the pull request.

Normally an #m would live in a #p. Can you give that a go?

I'd have said the math wasn't being processed based on the first screenshot.
Looks like *nothing* is being processed in the second screenshot.
Are your screenshots from Runestone hosting or "plain HTML"?
I can't think of recent changes on the PreTeXt side that might be responsible.
Doesn't look that RS pull request ever added an example to the PreTeXt Sample
Book, so from my perspective there's not much to go on. Did it ever work?

To me it looks like HTML characters (less than sign) are being escaped at some stage where they should not be escaped.

I see something in the JS likely related to recent refactoring to remove a JQuery dependency. Will PR it to Brad.

And perhaps "somebody" could donate an example of a horizontal Parsons with math
to the Sample Book, once this is sorted. I'm sorta looking sideways at you
Sean, though there are others who may feel a greater sense of responsibility. ;-)

Suggestion: Add two problems on the same page. There turns out to be two issues - one is the JQuery one I mentioned; the other is a preexisting timing related issue with transforming HTML into the draggable block, mathjax loading, and re-rendering the blocks with mathjax. Having multiple problems on the same page makes it more likely that the timing issue appears.
I'm fixing both, but the timing one is more duct-tape work than a proper fix.

I will make a duplicate of this question (so there are two on the page) and push things up to Runestone to see how it looks there.

I think Vilma needs this live ASAP, so I might ditch the horizontal mode temporarily.
There are two other horizontal Parsons problems in APEX I can keep for testing.
