#58017: Exception thrown when using array-data in URL query

 When using the following URL query:
     ?mtype=libraryitem&maps-tag%5B0%5D=children

 Then the following function:
     /wp-includes/blocks/navigation-link.php(129):
 block_core_navigation_link_maybe_urldecode

 will throw the following Error:
     Uncaught TypeError: rawurldecode(): Argument #1 ($string) must be of
 type string, array given

 because the function wp_parse_args (that is used in the function above)
 will parse the given URL to return query-keys ending with []-characters to
 be an array and not a plain string, see output from print_r:

 (
     [mtype] => libraryitem
     [maps-tag] => Array
         (
             [0] => children
         )

 )

 But the function rawurldecode that is used below expects the argument to
 be a string, not an array.


 This suddenly started happening, I assume after 6.2 got released on March
 29, 2023.
