Moving child nodes with keyboard does not work due to nodes being moved by absolute position instead of relative position

[Pjaerr]

👋 I've just been playing with this example and I noticed that the default keyboard accessible controls built into ReactFlow aren't working as expected here due to the parent - child node relationship. If you try and move child nodes with the keyboard, the just move up and to the left. It looks like this is as if they are being moved like position = positionAbsolute + movementSpeed but due to them being child nodes, position is relative, not absolute.

Is this an issue worth filing in the main ReactFlow repo? I couldn't easily recreate on any of the official example sandboxes so thought it was worth raising here first.
