Works like a charm, and good catch!  How did you find the culprit?

With `jit-lock-debug-mode' I get as far as getting a message

  Error running timer ‘jit-lock--debug-fontify’: (end-of-buffer)

which clearly tells we're trying to moe farther than end of buffer but
still there is no indication where we're doing that.  Do you have some
trick I'm not aware of yet?

Bye,
