Custom Adornment breaks curve editing

Background:
I am using an SfChart to display and edit a pressure curve used by some hardware. The user clicks a button to enter an edit mode at which time I make visible the adornments which they can use to alter the pressure curve. This works great right now.

The ask:
The designer would like me to make the adornments much smaller. So small that trying to drag the points with a finger is very tough.

What I would like to do:
I would like to use a custom adornment that has a large transparent target area (40x40) with a smaller visible ellipse (15x15).

The problem:
When I switch to using a custom adornment which is a DataTemplate with a Grid with an ellipse in it, dragging becomes nearly impossible. In the debugger I see that the DragStart fires each time but the DragDelta and drag end fire very rarely. If I switch back to a built in adornment then I see the drag events fire correctly.

Any idea what the issue is?
Thank you.
