ScenarioPicker: Reveal moves the content the right way; Launch is one-shot; the scrollbar takes no focus; the picker holds focus itself so the scene's background-click deselect is back on

Browse source 
ScenarioPickerVerify builds the real scenario list after a layout pass and arrows to every row, up and down, requiring each wholly visible; Launch by click, second click and Submit runs once.
