Comment:

 @michael.bucklin Ah, it happens in the admin, gotcha!

 Query args aren't modified in the front-end, but
 `wp_admin_canonical_url()` is run in the admin to remove query args like
 `?message` on page load.

 The culprit is this line in the function:

 {{{
 $current_url  = set_url_scheme( 'http://' . $_SERVER['HTTP_HOST'] .
 $_SERVER['REQUEST_URI'] );
 }}}

 Here, `$_SERVER['REQUEST_URI']` contains the wrong information. No idea
 where the query var gets modified though...
