There are some recent (week old) changes to org-fold that changes fold/emphasize behavior. Before the changes, I used to have
(setq org-fold-catch-invisible-edits 'show-and-error) in order to prevent accidental write in the following places: :PROPERTIES:|... But now, hidden emphasize symbols are considered "folded" so when I write: *Hello*| and about to press "space" I get a warning. I think this is a regression. I don't want to change the `org-fold-catch-invisible-edits' variable to something else because I worry more about accidental edits in real folded regions. I don't understand why emphasize markers are treated as folded text. `org-hide-emphasis-markers` is set to non-nil. Best, -- Daniel Fleischer
