A ?view= link opened without a session spun forever: the gate rendered
the bare view when the session check failed, so the plugin runtime never
started and the view never registered. A regular browser now keeps the
link in sessionStorage, shows the normal login and opens the link again
after any login, including redirect logins. Only same-origin paths with
a view are restored. The desktop app, embedded sign-in frames and guest
views keep their current behavior.
