AFAIK this is a side effect of `global-font-lock-mode'.  The global mode
(on by default) enables font-lock-mode in any buffer, while the default
value of `font-lock-mode' remains nil.

But OTOH the font-lock-mode related display functions kick in only when
certain variables are not nil (like `font-lock-keywords').
