missing content due to latexmath macro

[wmat]

I noticed today that some content isn't rendering in places where the latexmath macro is being used.

For example, in Chapter 20.8 Single-Precision Floating Point Compare Instructions, the first paragraph looks like this:

As you can see, there is no registers within the braces, only an equal sign, less than sign, and less than or equal sign. The source for that piece of the paragraph is:

(latexmath:[$\mbox{\em rs1} = \mbox{\em rs2}$], latexmath:[$\mbox{\em rs1} < \mbox{\em rs2}$], latexmath:[$\mbox{\em rs1} \leq \mbox{\em rs2}$])

All occurrences of the latexmath macro need to be auditted to ensure they're still producing the correct output.

The following files contain the latexmath macro:
colophon.adoc
f-st-ext.adoc
intro.adoc
m-st-ext.adoc
machine.adoc
mm-formal.adoc
rv32.adoc
rv64.adoc
supervisor.adoc
zfa.adoc
zfh.adoc
zfinx.adoc
zicsr.adoc

Do you know what changed that made these stop working? Is this about HTML output specifically?
