There used to be several types of overlays for headline folding, drawer
folding, and block folding. One of the recent commits made all the
overlays use headline type. As a result all the overlays are merged into
a single overlay upon folding. This was done to reduce the total number
of overlays present in an org buffer, which degrades Emacs performance
on huge org files (see the discussion in [1]).
What you observe is a consequence of that change. Now, all the drawer
overlays are destroyed when you fold a heading. Isearch would
only see a single huge overlay and unfold it alltogether.
I am currently working on a patch to rewrite the whole folding system.
Your issue should disappear once it is applied.
Meanwhile, you may, for example, advice
org-fold--isearch-filter-predicate to re-fold drawers during isearch.
Best,
Ihor
