Thanks for this Emanuel, I've doctored my init.el and put the above in
it, at the end, which is where I always put temporary/testing code,
unless it goes into my setup-testing.el. I then ran it when my mouse was
on the problem text in a gmail, and this is what it found -
╭────
│Face: ((:foreground #5e5e5e) (:foreground #5e5e5e) (:background #727272))
╰────

Perhaps I'm misunderstanding you, but how can I customise that? Its got
no name or handle that I can hook on to!
