When font-lock-mode is active, char-property-alias-alist contains
'(face font-lock-face). Thus, 'face text property is inheriting the
value of the 'font-lock-face property. It is not the case when
font-lock-mode is disabled. Unless we can forever rely on the
implementation detail that 'font-lock-face is always equivalent to the
'face property, there is no easy way to tell which faces will be applied
to the fontified buffer with enabled font-lock-mode.

Best,
Ihor
