Panels: Display...NOT showing color picker "Background - Solid color"?

When I want to change my Background color (“Background - Solid color” already selected/active), the color picker is not showing? I have to click on “Solid color”, then select “Solid color” again for the color picker to shows up?

It would be logical that when “Solid color” is active the color picker is also active!
This saves a lot of steps to assign a new background color when working in the mode of “Background - Solid color”.

Update: This only happens in “Wireframe” mode. When in :shading" mode it woks logical.
