Currently, it appears that if an imported Path has a Rotation Property already applied to it in the SVG code itself, Studio is capable of detecting, reading this value, and displaying the value in the Studio interface.

However, it suffers from glitching and being unable to perform a manipulation when the value is changed in the Properties. See attached video.

Repro Steps:

1) Download the attached NamedPaths.svg
2) Create a Project with a MainPage.xaml, and import the attached NamedPaths.svg into the RootGrid.
3) Select the red Diamond on-Stage, then navigate to the 'Transform/Render Transform' section of its Properties Panel.

Observe how it is correctly reading the value of the rotation set in the SVG code itself.

4) Change the Render Transform Rotation Value by clicking and dragging the mouse over the input field.

Observe how it rotates, then suddenly snaps back to its original position, rendering in-Studio rotation impossible.

Expected Results: Studio is able to Render Transform rotate any object.
