GuidedDraggingTool.js doesn't work well

Hi, everyone, I have a problem. I don’t understand. When multiple nodes are in a group, drag a node and GuidedDraggingTool.js will not display the guides.

Yes, if you look at the implementation of GuidedDraggingTool.showHorizontalMatches (and showVerticalMatches) you will see that it only considers other top-level Nodes. So it is explicitly ignoring other nodes within the group.

If you take out && part.isTopLevel from that predicate, does it work the way that you want? It’s on lines 159 and 254 of extensions/GuidedDraggingTool.js.

@walter thank for you answer
