Confirmed.

At this point, I feel that supporting isearch + text properties is an
uphill battle. I was hoping to contribute isearch.el patch upstream, but
apparently numerous other libraries (ispell, regexp-search, evil,
swiper) are relying upon invisibility being handled in very specific
way, using overlays. Considering that using overlays is no longer slower
compared to text properties in Emacs 29+, I am thinking of slowly
switching back to using overlays for folding for newer Emacs versions.

For your problem, just add (setq org-fold-core-style 'overlays) early in
your config. It should fix the issue.

Org mode development branch will have `org-fold-core-style' defaulting
to 'overlays now as long as Emacs version is recent enough to handle
overlays efficiently.

Handled.

Thanks, I'm therefore closing this bug report.
