mailto-Links aren't rendered correctly
When a mailto-Link is inserted, e.g. "test@example.com" it isn't rendered correctly as a mailto, instead it gets the current URL as prefix, e.g. https://cloud.example.com/remote.php/files/some/weird/folder/structure/mailto:test@example.com and so points to nirwana. Expected Behaviour: Render it correctly, so the mail program opens on click.
