Request Body Value with an '&'

On SwaggerHub pages, I am attempting to return an authorization token.  The password parameter within the Request Body (x-www-form-urlencoded) will not work when an ampersand (&) is part of the value.  It works fine using Postman or Visual Studio Code, but does not work within the Swagger pages.  I have even used the encoding: password: allowReserved : true, but to no avail.  Anyone else have this issue or a workaround?
