    Revert part of recent commit 85544f8ef5 (bug#40808)
    
    * lisp/isearch.el (isearch-lazy-highlight-search): Remove recent fix of
    lazy-highlighting of hidden matches.  In emacs-27 leave only the fix for
    lazy-counting of hidden matches when isearch-lazy-count is non-nil.
    
    ; Do not merge to master.
