No, but is is perfectly permissible to ligate f and h anyway, just like you
can (or should) ligate f and j, and g and j (if the glyphs would overlap).

U+FB01 is a compatibility character that is best avoided to use at all. Formation of
of an f and i ligature should not depend on if the character U+FB01 is supported
or not (though it is likely to be supported if f and i are ligated).
