The issue is still easy to reproduce:

>>>

* h1
aaaaa
* h2
bbbbb
* h3
bbbbb
* h4
ccccc

<<<

Fold all. On * h1 call swiper-isearch, enter bbb and select the first match. -> h2 cannot be unfold anymore.

If you repeat it and select the second match then h3 cannot be unfold anymore, but h2 works again.

(org-fold-core--clear-isearch-overlays) still fixes the buffer.

The fix did fix it for me, and the problem went away. It did seem to introduce
a new problem with searching in a buffer with Swiper, where the search would
fail or throw an error or require me to collapse headings before it would work,
but that hasn't happened in a while and I didn't try to debug it.
