Currently, in a Setter within a Style, once the Setter created, it can be selected, and changes to the Style's Properties can be 'keyed'.

However, it appears that in the case of Colour changes, although the Colours are updated as expected on-Stage, the Brush Editor exhibits some strange 'snapping' Behaviors where the colour that is displayed upon making a selection, does not match the colour displayed on the Stage.

See attached video.

Repro Steps:

1) Download, unzip, and open the attached 'Setters_Project' in Noesis Studio.

2) On the Stage of MainPage.xaml, identify any of the Buttons at the top of the Page, and right-click any of them and enter its Style for Edit.

3) Once inside of the Style, navigate to the Interactivy/Setters Panel, and click on the Setter there to edit the Setter Property Values on the Stage.

4) In the Style's Properties Panel, change the 'Foreground' property to a different Color.
Observe how upon any new colour selection, the Brush Editor's 'Picker' components snap back to a colour that doesn't correspond to that chosen and displayed successfully on--Stage.

Expected Results: Picking a new Colour in a Style's Setter, displays the new colour successfully in the Brush Editor Panel.
