Current behavior

When using useProximity when a node is dragged, a console error is thrown

Expected behavior

There should be no error thrown when dragging a node

Minimal reproduction of the problem with instructions

• visit the useProximity storybook demo https://reaflow.dev/?path=/story/demos-proximity--simple
• Open chrome dev console
• begin dragging a node
• notice the error Cannot read properties of undefined (reading '0') which stems from useProximity's getCoords call

The getCoords definition expects the call to include a layoutXY property like in useNodeDrag

What is the motivation / use case for changing the behavior?

Correct usage of the getCoords function
