Hello,

I've been experimenting a lot around the DraggableContainer and I think I've stumbled into an issue where the position of the container is messed up.

Here's a way to reproduce:

1. Starting with the DraggableContainer D in a FlowLayout (vertical) F, window in its default non-maximized state
2. Drag D around
3. Maximize the window
4. The container is usually pushed out of the window
5. Back to the non-maximized window state
6. The container doesn't come back to its original position

I'm not sure where the issue is. I've spent some time debugging, without success.
Here's what I've tried so far:

• Changing the DraggableContainer's parent
• Changing the DraggableContainer's child
