smartNavigation: false
I'm late here but we have a (currently undocumented) map constructor option called smartNavigation, which is a boolean. To turn of superpan, use:smartNavigation: false
when creating a map. We'll get this documented.
It appears that disabling smartNavigation automatically enables scrollWheelZoom and it cannot be disabled by either map init options or disableScrollWheelZoom(). Without the ability to disable scroll hijacking we can't use esri maps in our scrollable pages.
