Comment(by mikeperry):

 window.name is another vector for linking across automatic top-level
 redirects. If we try to find a non-prompt-based solution, it will need to
 be cleared for them, too. If we have a prompt, it might be OK to leave it,
 to allow things like ancient federated login systems that abuse
 window.name.
