How to use componentsAtPoint() if the object and the drag target have different parents?

I am making a card game where the player must hit the cards lying on the table.
The logic of the game forces me to strictly break everything down into components, as a result I have the following structure
game:

• TableComponent (position 0:0, size 100:100)
  • cardOnTable1
  • cardOnTable2
• HandComponent (position 0:100, size 100:100)
  • card1
  • card2

How can I check if a dragged card component lands on the cardOnTable component?

componentsAtPoint propagates down the component tree that it is run on, so just run it on the world, if your components live in a subtree of the world, otherwise use it on the game, and pass in the globalPosition.
