Requests outside the document's bounds should not trigger an error #296
Description
If the request is for a position that is outside the document's range, we should return nothing instead of logging an internal error. Although it is possible there is an internal document synchronization bug on the server's side, there is equally a possibility of a client sending the server invalid parameters.
