Encode URL for URL param redirects

Lets say I am not logged in and try to access
https://website.com/wp-admin/post.php?post=91&action=edit
and then login using Mini Orange SSO
the return URL after login changes the & (ampersand) to
&am p;amp;
(I put a space between the am and p because otherwise it just converts it here into another ampersand)
which is not a correct URL as far as WordPress is concerned.
Is there a way to tell Mini Orange no to do that?
