When opening the browser with 'All non-private windows from last session', the tabs should also retain their history because it's useful.
Likewise, in Safari, when I reopen a previously closed tab, all the history of that tab is also available. I find this useful when I close it accidentally, or when revising some history. Thanks
(Btw, a lot of my feedback will be related to Safari because I find that they did get a lot of things right, but have dropped the ball in many areas, which you guys have thankfully picked up)
