In any case where font-lock-fontified is nil font-lock-fontify-buffer will properly refontify the whole buffer, but font-lock-flush and font-lock ensure will not do anything. I don't know what causes that variable to be nil in the first place, though.

I am not sure if this is related. But in order for hi-lock-file-patterns to work in a text-mode buffer, I need to do the below because font-lock-fontified is nil for text-mode (as technically there are no comments or keywords to highlight in that major mode).

(defun modi/hi-lock-enable-in-text-mode ()

(setq-local font-lock-fontified t))

(add-hook 'text-mode-hook #'modi/hi-lock-enable-in-text-mode)
