[Juri Linkov]

branch: master
commit f247fa5d5ce7cb34f23c979c17b14c5713eb5490
Author: Juri Linkov <juri@linkov.net>
Commit: Juri Linkov <juri@linkov.net>

    * lisp/isearch.el (isearch-delete-char): Reopen hidden overlays (bug#52248).
    
    (isearch-filter-visible): Move text-property-not-all higher
    to not call isearch-range-invisible on inhibit-isearch text.
    Remove min/max since arguments are always in the right order.
