Loss of Left Pane Scroll Function when Starting App with Pane Closed

When you start the app with panes closed as suggested in Issue #703 you lose the ability of the scroll function within this pane. Does anyone know how to avoid this?

Instead of panes: { left: { open: false },

You need to use panes: { left: { open:'none' },
