can't go back from a redirect to a security warning
- go to a link that redirects to a website with an invalid or expired cert, https://duckduckgo.com/l/?uddg=https%3A%2F%2Fexpired.badssl.com¬rut=duckduck_in
- press back
it goes back to the redirect and shows the security warning again. afaik, they are provided by epiphany, not webkit
