The panel kept its own selection (a pstate nothing else read), so a
click only highlighted the row: the status bar navigator, Fit Artboard
in Window and Actual Size stayed on the previous artboard. The panel's
selection is now the view's active artboard (View::artboard): a click,
Move Up/Down and New Artboard set it, and the highlight follows the
navigator, per document, as in the reference app.
