Another possibility for pop-behinds (and perhaps popups in general)
is to close any popups that the user hasn't interacted with when the
user leaves the site (for some definition of site that's probably
broader than single page) by navigating away or closing the tab.

             What I was walling in or walling out,
             And to whom I was like to give offense.
