Quadratic bezier drawing: Select and align both on-curve and off-curve points

I found that when drawing quadratic beziers, I seemingly can't select both on-curve off-curve points for alignment/transformation operations.

Eg I throw some wild points down like this and go to select some

but only the oncurve are selected

Reproduce the quadratic-bezier selection case in the browser-based font editor using the attached examples. Trace the selection and alignment/transformation entry points for on-curve and off-curve points; done when both point types can be selected together and participate in those operations.
