Steam controller / deck : Right Pad input style is incorrectly set to "as joystick"

I noticed that when using the Steam Controller, (and most likely the deck as well) the recommended (default) gamepad configuration sets the right pad to the "as joystick" style input instead of the "joystick" style

"Joystick" would be the better option.

"As joystick" sends a signal to the game only while you move your finger is moving across the touchpad, attempting to emulate a mouse.
"Joystick" style, alternatively, continuously sends a signal based on the physical position where your thumb rests upon the pad.

This should be very obvious when you try control the in game radial menu with the right pad, because in "Joystick" style the radial menu will work, and when set to "As joystick" it doesn't.
