Favorites pinned should survive Edge restart

[Thilo Langbein]

I pin the favorites bar to the right side.

After Edge restart the favorites bar isn't pinned anymore.

I would prefer that pinning status is retained.

I agree that the state of the sidebar when Edge closes remains the same when Edge is restarted; this should also be the same for all sidebars state (e.g. History etc.)
