When adding a 'subPath' for REST calls for a homepage, then the URL has an incorrect extra / breaking the REST call

When the URL is for the homepage, and the REST Mount is for example called 'restapi', then the URL becomes f.e. when the subpath = 'html' something like:

http://localhost:8080/site/restapi/./html

this however is interpreted as http://localhost:8080/site/restapi/html. The URL that is created should be

http://localhost:8080/site/restapi./html instead
