Repro Steps:

1) Create a Page
2) Place a Rectangle Shape into the Root Grid
3) Right-Click on the Rectangle, and from its context menu, navigate to "Path", then select "Convert to Path".
4) Activate the Path Selection Tool (A), and Ctrl+Click on any Path Point in any of the corners of the rectangle. This will convert the corner to a curve.
5) Still with the Path Selection Tool in-hand, click on the Path Point of the recently converted corner, and drag the mouse in any direction.

Observe that both the Path Point, and the joined Path Point Handles move in-sync across the canvas.

6) With the Path Selection Tool (A), Ctrl+Click on another corner of the rectangle to convert it to a curve.
7) Click on the Path Point in the corner converted in Step 6).
8) Nudge the keyboard ArrowKeys in any direction.

Observe how the path Point moves without the Path Point Handles, which stay in the same position.

Expected Results: Both moving a Path Point by Mouse, or by Keyboard ArrowKeys produces the same interaction.
Expected Results: Path Point Handles move along side Path Points when repositioned.
