I think this was fixed last year-ish if I'm reading the change log
correctly.

Currently, font-lock-ensure calls the value of
font-lock-ensure-function, which has a default value of

  (lambda (beg end)
    (unless font-lock-fontified
      (save-excursion
        (font-lock-fontify-region beg end))))

If global-font-lock-mode is on, it's jit-lock-fontify-now.

So I think this now works better, and I'm closing this bug report.  If
this is still an issue, please reopen.
