Mystery solved. (I had to cook dinner and then I paid my dues
to politicians on TV -- for a short while)

Looking again at your message the `texmathp' rang a bell

(some problem we discussed here months ago, which I have forgotten
now)

turns out I had this setting:

texmathp-search-n-paragraphs is a variable defined in ‘texmathp.el’.
Its value is 0
Original value was 2

setting it back to 2 solves the issue.

Best wishes,
