    " DynamicSideContent one (app 138); the controller behaviours are wired the
    " same way: breakpointChanged carries its currentBreakpoint to the backend
    " and enables the Toggle button on S, the Toggle press calls the control's
    " own toggle( ) through control_by_id, and the Slider resizes
    " the container's DOM node through the css control method - sap.m.Page has
    " no width property, exactly the gap the original's jQuery width( ) works
    " around. style.css is injected as a core:HTML style leaf.
