Just to clarify:
1. If font-lock-mode is off, you should use (propertize … ‘face …)
2. If font-lock-mode is on, you should use (propertize … ‘font-lock-face …)
If you create a buffer interactively, font-lock-mode is on (at least in the
latest version of Emacs, not sure which version of Emacs are you on). But if
you create a buffer programmatically (as you did in the code snippet),
font-lock-mode is off.
