Should that restore sessionStorage data ?
Aren't you making sessionStorage much more complicated while the same use cases are covered by localStorage ? 
sessionStorage could be optimized to be just a volatile amount of data in memory, but these requirements require sessionStorage to implement the same disk IO heuristics, and a complex heuristic to decide when to erase sessionStorage completly.

I vote for the data to be present just while a page is open or is restored from history or by going back.

Thank you.
