Subject: bug#76669: read_key_sequence discards events without attempting remapping

Suppose we want to use local-function-key-map to translate
s-<down-mouse-3> to <down-mouse-3>.  If we don't have a concrete binding
for s-<down-mouse-3>, we never attempt to translate it: instead,
read_key_sequence discards the down event and skips right to
s-<mouse-3>, which we *can* translate.
