Comment (by ChopinBach):

 @timmydcrawford Great catch on this! To solve two problems at once,
 instead of changing the conditional to check if it is an array.  Just
 change the line where `$terms` is assigned to read `$terms =
 wp_parse_id_list( $request[ $base ] );` That should enable the csv list
 support for updating/creating posts with multiple categories.  I haven't
 tested it, but it should work.  Adding in a test case would be nice too. I
 will test it myself tomorrow and see if I can help out.
