Please see the attached (3rd) revision of the patch.

However, the tests still fail when ran via `make test'.  See below.

I cannot figure out why these tests pass when ran from inside of Emacs
but fail when ran via 'make tests'.  I found in `default.mk' that Make
runs `ert-run-tests-batch', but even that *passes* from within Emacs:

1. load `testing/org-test.el',

2. evaluate `ox-html/mathjax-legacy-scale-message-in-buffer` test in
`testing/lisp/test-ox-html.el', and

3. run `M-: ert-run-tests-batch'.

It produces the following output in the `*Messages*' buffer:

  Running 1 tests (2022-11-05 23:17:56+0100, selector ‘t’)
  Converting legacy MathJax scale: 20 to 0.2
     passed  1/1  ox-html/mathjax-legacy-scale-message-in-buffer (0.008186 sec)
  
  Ran 1 tests, 1 results as expected, 0 unexpected (2022-11-05 23:17:56+0100, 
0.010790 sec)

It seems that some part of the *batch* testing swallows the messages in
a way that makes `(current-message)' work incorrectly in tests.

Any ideas?  Asking for an Emacs veteran.  :)

P.S. As a workaround I also tried to set `set-message-function',
dependency-injection style, but it did not work either.
