The current behavior of reveal-mode was designed while using it with
outline-minor-mode in elisp buffers.  It is tuned for such a context and
might indeed need different tuning in a different context.

The behavior you seem to want is actually simpler than the current
behavior (in other words, I first implemented the behavior you want and
then added code to keep the overlays open even after the cursor moves out
of the overlay), and it should be easy to change the code such that you can
choose between different behaviors.

But please don't just remove the code that implements the current behavior.
