Question: Is the NumberBox's Spin Button Disabled state correct?

[mdtauk]

Looking at the NumberBox test page in the MUXTestApp - When the compact mode spin buttons are disabled, there is a backplate visible for both the up and down buttons.

It looks a little odd, so I was wondering if this is actually the correct design for these buttons?

Both buttons disabled

Top button enabled, bottom button hovered

Top button pressed, bottom button enabled

By way of a comparison, here are the Inline spin buttons

both buttons enabled

both buttons disabled (these also show a backplate when disabled
