Opt-out shortcode iframe path not correct

Hi,

I’m trying to use the opt-out shortcode on a HTTPS site, but the iframe refers to an incorrect URL, because the front slashes are missing.
Thereby the URL looks like this:
https://Site.URI/Track.URI/index.php?module=CoreAdminHome&action=optOut&language=en

Can you add two front slashes to the URL, like this: //Track.URI…
That way you also avoid the loading of unsecure content or resources.

Thanks
