Workflow optimization for missing nodes

### Feature Idea

When I dragged in a workflow with a missing node, the missing node was marked red, and then I encountered two problems:
1. When I click on any node in the workflow, the mouse will automatically select the current node. Unless the node is removed by right-clicking, my mouse will always be strongly bound to this node. No matter where the mouse moves, this node will be tracked. No matter where, this is so annoying!
2. Because the node is missing, the specific parameters of the missing node cannot be viewed, so that it can be better replaced with other nodes.
If you want to optimize the above two problems and avoid strong binding between nodes and the mouse, you can check the specific parameters of the missing nodes;
