[Bug]: Drag element, event onDragStart #6734

The issue you've described seems to be related to the handling of edges in a combo when using the onDragStart event in G6 version 5.x. Specifically, the problem arises because the function getSubgraphRelatedEdges only considers internal edges and not external ones, causing visual discrepancies where edges from outside nodes to combo nodes appear to fade into the background.

To address this issue, you might need to modify the logic in the getSubgraphRelatedEdges function to include external edges as well. This would ensure that all relevant edges are considered during the drag event, maintaining the correct visual hierarchy.

If you need further assistance or a more detailed solution, please let me know, and I can help guide you through the process of modifying the code or suggest alternative approaches.
