Repro Steps:

1) Create a New Page
2) Select the Background property of the master Grid of the page.
3) Paste in a desired hex value (eg: #FF91bc39)
4) Press the '+' icon to add this value to the Page Resources as a Universal Colour Resource.
5) With the Grid still selected and the Background property panel still open, click the newly-created colour swatch to apply it to the Grid.
6) Navigate to the 'Resources' tab, navigate to the Page's resources, and find the saved colour Resource, and click on it.
7) Using the mouse, drag the colour pip across the Colour Selector in the upper right of the screen to change the colour.
Observe how the colour of the Grid element changes.

8) Instead of dragging the colour selector pip, type in a new hex value into the hex value input field (eg: #FFbfbfbf)
Observe how the Grid's colour does not update in real-time.
Observe how once a hex value is typed in, even the ability to update with the mouse on the colour wheel stops working.

9) Navigate back to the Grid element, and remove the colour binding, before immediately re-applying the colour resource.
Observe how now, the Grid is coloured correctly to the latest typed hex-value specified.

Expected Result: Any element using a universal colour resource updates in real-time whether a colour is hand-selected using the colour wheel, or changed via a typed hex-value.
