I tried in a buffer with over 19,000 files.  I should have experienced a
problem (no matches found, nothing changed) if font-lock would be
related.  But every function involved always found matches hundreds of
screens below the current position.  I reloaded the buffer after each
experiment to be sure only the currently visited area was ever displayed.

OTOH, I did see the match-data issue occur.  Maybe this is the only
reason of our problems.  I would focus on trying to understand that
problem.

It's a not-so-nice inconsistency, but ok...
