Mouse pointer capture is lost when moving out of Win2D Canvas control

[d2phap]

I'm using Win2D to draw an image, and implement panning feature.
The problem is when I press, and move the mouse cursor out of the Canvas control, the pointer capture is lost.

Any idea to prevent this?
Something similar to the setPointerCapture API in JavaScript: https://developer.mozilla.org/en-US/docs/Web/API/Element/setPointerCapture

Thanks

<win2d:CanvasControl
  x:Name="canvas"
  Draw="canvas_Draw"
  PointerEntered="canvas_PointerEntered"
  PointerMoved="canvas_PointerMoved"
  PointerPressed="canvas_PointerPressed"
  PointerReleased="canvas_PointerReleased"
  PointerWheelChanged="canvas_PointerWheelChanged" />
