I had misunderstood the question above. For the record, when a
callback defined in the IDL to return a boolean actually returns a
non-boolean value, it is my understanding that WebIDL requires that
ToBoolean() be applied to the return value. So returning nothing or
"undefined" is equivalent to returning "false".

Sorry about the miscommunication here.
