"Unsupported Nodes" are not marked red

### 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

After a recent ComfyUI update I get the error:
`"Workflow contains unsupported nodes (highlighted red). Remove these to run the workflow."`

Among the affected nodes are ComfyUI-GGUF nodes, KJNodes and comfyui_controlnet_aux nodes, which are essential for my workflow and system.

Affected nodes should be marked red (as stated in the error message)

### Actual Behavior

Affected nodes are not marked red (as stated in the error message).
Tested in Firefox 144.0.2 and Chromium 139.0.7258.154

### Steps to Reproduce

Any workflow with added GGUF nodes or KJNodes.
