I have a problem with drag&drop Node over Link between Nodes inside and outside a Group.
Nodes 1-3 are placed inside Group, Nodes 4 and 5 - outside.
mouseDragEnter are called for Link12 and for Group when drag Node5 over Link12.
mouseDragEnter is called for Link34 but isn’t called for Group when drag Node5 over Link34.
How to teach DraggingTool to call mouseDragEnter for Group when Node5 is dragged over part of Link34 that placed inside Group?
