Help! Issue with the sidebar queue thumbnail display.

### Custom Node Testing

- [x] 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)

### Your question

How can I make the thumbnail in the QUEUE section of ComfyUI's sidebar display the last generated image? Currently, the thumbnail shows the first generated image.

### Logs

```powershell

```
