Steps to reproduce:
Any tab that is pinned loses its scroll position upon reloading with the appropriate shortcut. It should not do that and should save in all instances until the tab is manually closed.
Even when the domain is changed, the history of the previous tabs should maintain all of the previous scroll positions just like Chrome.
