Comment:

 Noting that `wp_parse_str()` is currently a simple wrapper for PHP's own
 `parse_str()` function. The behaviour we are seeing here is also
 [https://www.php.net/manual/en/function.parse-str.php#76792 documented in
 a user note].

 Since we already have this wrapper we could include a possible fix there.
