Some HTML emails can trick messagelib into opening a new browser window when displaying said email as HTML

Summary

Some HTML emails can trick messagelib into opening a new browser window when displaying said email as HTML. This happens even if the option to allow the HTML emails to access remote servers is disabled in KMail settings. This means that the owners of the servers referred in the email can see in their access logs your IP address (CVE-2018-19516).
