Enhanced Color Selector Undocking

Hi, 

I was excited to see the updated about the enhanced color selector! In the article explaining how it works it says, "click the Undock icon on the upper right to move it to an adjustable floating window, as shown above." I took this to mean you could undock the color selector and it would remain open in its window just like you can undock the timeline or states window. However, when I try to adjust more than one shape the color selector won't remain open.
