Any chance to fix also bug#40808? It's still open because there is no solution for isearching invisible text in org-mode. Here's a short test case that demonstrates the problem in org-mode: 0. emacs -Q 1. visit emacs/etc/ORG-NEWS 2. isearch for "http": C-s http C-s C-s C-s ... it eventually stops at org links where "http" is invisible, such as [[https://orgmode.org/worg/library-of-babel.html][here]] The problem is that org-mode puts the text property 'invisible' only when the link is scrolled into view, I guess it puts the property using font-lock. So it seems org-mode needs to use font-lock-ensure on the line with the next search hit before calling isearch-filter-predicate on the found occurence.
