Currently, if a Shape Element is set as the Clipping Path of another Element, it will convert the Shape into the Element's 'Clip' Property Value.

However, when doing this operation with the new CornerBox and Gear Elements, when the Clipping Path is applied, no value is displayed in the Element's 'Clip' Property until the Page is restarted.

See attached video.

Note that related to this, it also appears that certain Shapes do successfully display the 'StreamGeometry' value, but take a restart to display them as a blue 'Local Value' change.

Repro Steps:

1) Gather a PNG image of your choice, and place it in the Directory you will be working in for the rest of the repro steps.

2) Create a Studio in the Directory of Step 1), featuring a MainPage.xaml

3) Introduce an Image Element to the Stage, and set it to display the PNG prepared in Step 1).

4) introduce a CornerBox or Gear Shape to the Page's root Grid, adjacent to the Image Element introduce in Step 2).

5) In the Navigator, multiselect both the CornerBox/Gear Shape and the Image in the Navigator, then right-click on the CornerBox/Gear Shape, then from its 'Path' Context Menu category, select 'Make Clipping Path'.

Observe how the Shape is removed from the Navigator, leaving only the Image behind.

6) Select the Image in the Navigator, and under its Appearance Properties category, identify the 'Clip' Property.

Observe how the 'Clip' Property displays a value of 'None'.

7) Close and re-open MainPage.xaml, and select the Image Element once again.

Observe how the Image now displays a 'Clip' Property value of 'StreamGeometry'.

8) Repeat Steps 4) to 7), but instead of a CornerBox or Gear, use a Star Shape.

Observe how when a Star is used as a Clipping Path, the 'StreamGeometry' 'Clip' value displays instantly as soon as it is set to that role. However, it does not display as a 'Blue' local Property value.

9) Restart MainPage.xaml

Observe how now, the 'StreamGeometry' 'Clip' value displays with a Blue colour coding.

Expected Results: Elements succesfully displays their Clip value when applied from a CornerBox or Gear Shape as a clipping base.
Expected Results: Elements show their 'Clip' value as Blue (changed Local Value) immediately when the StreamGeometry value is applied without requiring a restart.
