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).

    ;; Enable `hi-lock-mode' in `text-mode' too
    ;; The hi-lock fontification will not be visible (the
`font-lock-keywords'
    ;; variable will not be updated unless `font-lock-fontified' is already
`t'.
    ;; This was derived by studying the definition of
`hi-lock-font-lock-hook'
    ;; function.
    (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)
