After switching the workflow, the model that was switched in the previous workflow is automatically initialized.

### 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

The initial model is DM2.ckpt. After selecting another model, choosing another workflow and returning, the model will be initialized to DM2.ckpt.

### Actual Behavior

I have many workflows. After modifying the model of one of the workflows, I switch to another workflow, then return to the previous workflow. The model that was switched to before becomes the original model again.

### Steps to Reproduce

The latest version of comfyui has all workflows set up in this way.
