Comment (by DvanKooten):

 What about checking if the returned filter value is an array (which it
 expects right now) and if it is, proceeding with the function as it
 stands. If it's not an array, return early using the return value of the
 filter.

 {{{#!php
 if( ! is_array( $atts ) ) {
    return $atts;
 }
 }}}

 The process could be reversed by checking for a boolean, but as the rest
 of the function uses the value as if it's an array now anyway I think that
 would make less sense.

 That would be pretty much in line with what the other short-circuited
 functions do as well.
