Inline datepicker not rendered when disabled

Inline datepicker not rendered when disabled

Create an inline datepicker with the disabled option or call the disable method later, and you don't see any calendar at all.  It would be very nice to just be able to disable the visible calendar, i.e. turn off callbacks, but levae it up for viewing!
 
Is this a bug?  Seems so to me...
