832541 - Preload localStorage for dormant tabs after session restore

Status: RESOLVED INVALID

(Core :: Storage: localStorage & sessionStorage, enhancement, P5)

Description

[Honza Bambas (:mayhemer)]

bug 600307 introduces localStorage data early async preload.

There was a suggestion to do this async load also for tabs that are inactive (dormant) after session restore.  With bug 600307 we do it only after user switches to a tab.  This could be a significant improvement mainly for mobile.

It's not clear this enhancement concept makes sense anymore since in the intervening ~9 years the number of tabs that might be inactive/unloaded is extremely large. If we want something like this, it likely makes sense to provide an affordance for Session Restore and the Tabs UI to reuse/expand the existing notification path that a load will happen that already triggers our explicit preload API.
