Thanks for the pointer!

I've looked at your branch for inspiration, and my takeaway is that the
isearch-open-invisible-temporary route might be too involved for a
bugfix, especially if it's going to be reverted wholesale when your
branch gets merged.  Then again, maybe I'm not smart enough to devise a
solution.

I wonder if the path of least resistance couldn't be found in
org-cycle-hide-drawers: right now this function just skips over drawers
which are covered with an invisible overlay, but maybe it should not
skip a drawer if the overlay starts before it (i.e. the overlay is not
specific to this drawer but covers a whole containing section).
