Switching to Pen Tool removes Shape properties from the panel

I draw a shape with the Shape tool and can see all the properties in the Properties Panel: Mask or Shape icons, plus Fill, Stroke, etc. Then I switch to the Pen tool and the only properties that remain are the Mask properties. In the top menu bar my Pen tool is set to Shape, not Path or Pixels.

Didn’t the Properties panel show the Shape properties (fill, stroke) instead of disappearing when the Pen tool is set to Shape? Is this a bug or am I doing something wrong?
