The latest version of Comfyui cannot edit node connections

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Node connection is normal, drag and edit

### Actual Behavior

cannot edit node connections

### Steps to Reproduce

When using ComfyUI v0.3.43, I discovered a bug where node connections cannot be edited by dragging. I was editing on my original workflow and dragged the connection on the saved image node to disconnect it. However, the connection got stuck and stopped moving, resulting in a broken connection. At this point, I couldn't manipulate the connections on other nodes. I also found this issue in the latest kontext template node, not only when saving image nodes, but also when operating other nodes. I don't know if any friends have encountered such a problem？
The console also did not output any logs
