It's not possible to use PageBuilder using Map\Port matcher when SSL is enabled on the server.

Steps to reproduce:
1. Enable SSL on the server
2. Setup additional site accesses: fre, pol
3. Use following matcher configuration:

        match:
            Map\Port:
                80: admin
                443: admin
                8083: site
                8081: fre
                8082: pol

4. (in Admin): Add Anonymous permissions to User\Login for those site accesses and create languages they're using.
5. Go to Page and try to switch between site accesses

Result:
It's not possible to switch site access, an error like this is visible in the console:

Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://192.168.33.13:8081') does not match the recipient window's origin ('https://192.168.33.13:8080').
