Currently, Resources can appear in a scope where they are not accessible by the Property. They are furthermore able to be selected, but do not resolve when applied.

Repro Steps:

1) Download, Unzip, and open the attached Studio Project.

2) On the Stage, select the Black 'Button2' Element, then navigate to the Resources Panel, click '[Button] "BUTTON2" under 'MainPage.xaml'.
This will expose the Resources contained inline to the Element --- there will be a Green and a Black SolidColorBrush Resources.
Double-note that these Resources are in the Button at the Page level.

3) In MainPage.xaml, right-click on 'Button2', and in its context menu, navigate to 'Styles'->'Button'-->'Edit Current'.
This will open the Button Style in the Inline Dummy Style Editor.

4) Hover over both the 'Border' Property, click on its 3-Dot Menu, and select 'Apply Resource'
Observe how are available to pick from:

• The Red (Stored in the Page)
• The LinearGradient (Stored in GlobalResources)
• The Black and the Green (Stored in the Button in the Page)

5) In the Resource Selection Menu, click on the Red.
Observe how it applies as the Property Value as expected.

6) In the Resource Selection Menu, click on the LinearGradient.
Observe how it applies as the Property Value as expected.

5) In the Resource Selection Menu, click on the Black and/or the Green
Observe how the Resource is selected, but the Border's Property value shows a 'No Brush' and it appears to fail to resolve.

Expected Results: Resources that are resolvable, have their values displayed accurately in Studio.
