Currently, Resources in the Resource Panel offer a range of functions centred around the ability to drag and drop them from their location to another.

However, it is currently not possible to drag-and-drop the last-clicked Resource without 'selecting' it and forcing the opening of its Properties in the Properties Panel in the process.

Although this mostly impacts the fact that this makes it not possible to drag-and-drop a Resource from the Resources Panel to an Element Property, this is more generally a minor bug that likely shouldn't be happening.

Repro Steps:

1) Create a Studio Project featuring a MainPage.xaml

2) Navigate to the Resources Panel, and create a small collection of Resources inside of GlobalResources.xaml

3) Select any of the Resources created in Step 2), then select any Element in the Navigator.
At this point, the Resource selected in the Resources Panel should have a darker blue, whilst the 'active' Element in the Navigator has a brighter blue.
The Properties at this point should be displaying the Properties of the Element selected in the Navigator.

4) Without clicking anywhere else in the UI in-between, click-and-drag the previously-selected Resource in the Resources Panel. (don't worry about dropping it anywhere specific, just the act of clicking and dragging is enough)

Observe how clicking-and-dragging the Resource also selects it, and makes the Resource Properties appear in the Properties Panel.

5) With the Resource still selected, now click-and-drag a non-selected Resource.
Observe how the Properties Panel for this newly-dragged Resource does not take over the Properties Panel.

Expected Results: Clicking-and-dragging a Resource should not also select it and open its Properties.
