That probably has to do with expansion (a detailed explanation may be
given by a (Con)TeX(t) Guru :-)).

I think the best "fix" is to use the MkIV title mechanism (start... stop...)

That way you can do:
\startchapter[title={Footnote\footnote{Only where appropriate}},
bookmark={No Footnote}]
...
\stopchapter
