bug#56637: 28.1.90; [FR] Allow a way around font-lock-mode being unconditionally disabled in " *hidden*" buffers

[Stefan Monnier]

> Observed output: #("(message \"Foo\")" 9 14 (face font-lock-string-face))

`fontified` is not a text-property that belongs to font-lock but to
jit-lock, so its presence or absence depends on how font-lock is being
used (it can also be absent if you set `font-lock-support-mode to nil,
for example, and it can also be present even if you don't use font-lock
at all), so I would count this as "an incorrect expectation" rather
than as a bug.

Why do you care about those `fontified` properties?
