We do not currently process icons, so have no applicable behaviour here. However, if we did, I don't think that we would be comfortable fetching the icon when displaying the account chooser because that would disclose to the network and server that a given account was displayed. So we would likely try to fetch and cache the icon at registration time, perhaps turning it into a `data` URL. Likewise, we would not look kindly on a redirect to HTTP.
