On some launches the window opens with the sidebar collapsed even though it was visible when the app was last quit. View > Show Sidebar (ctrl-cmd-S) restores it.
Likely the same NavigationSplitView state-restoration quirk as #1: the split view's persisted collapse state and SwiftUI's idea of column visibility don't always agree at restore time. Deliberately NOT fixed by binding columnVisibility - we tried that and it made things worse (two owners for one pane produced blank sidebars). Whatever fixes #1 should fix this too.
Workaround: ctrl-cmd-S.
