Comment (by Cybr):

 Changing `array_filter( $query['terms'] );` to `array_filter(
 $query['terms'], 'strlen' );` would seem logical, but it may conflict when
 it's supposed to be `term_taxonomy_id`, where `(int) 0` would be
 undesired.

 This anonymous function as the filter callback would probably be better:
 `fn ( $term ) => is_string( $term ) ? strlen( $term ) : $term`

 I'm not sure if query parameter `?cat=42` will have `42` be an integer or
 number, but `0` wouldn't be accepted here anyway and causes the query to
 break in different ways due to `$GLOBALS['wp']->query_vars` being a hole.
