Fixed, on main; for Emacs >=29. Will not be fixed for earlier Emacs versions.

isearch + folding is very hard to make work reliably. We need to have
ugly workarounds. And not only for isearch - a number of other parts of
Emacs and third-party code exclusively support overlay folding.

Considering that overlays are no longer performance bottleneck, switched
back to using overlays for folding by default, except in Emacs <=28
where the overlays were slow. After Emacs 31 is released, folding via
text properties will be removed.
