refactor ••• list navigation (#1010)

There were some funny interactions between `<Button>` elememts with
`link` properties and the `<MenuItem>` elements that had click handlers.
Hopefully that's all sorted out now. I'd like to move toward `<Link>`
eventually and away from managing history on our own, but this is at
least consistent and functional.
