Task got interrupted while webpage refresh

### 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

When I refresh the ComfyUI webpage (like: http://localhost:8188), the running task will be canceled. I watch the network from browser and there is a '/interrupt' request and I don't know why.

### Logs

```powershell

```

_No response_

Reproduce the issue in the ComfyUI webpage at http://localhost:8188 while a task runs, then inspect the /interrupt request triggered by a refresh. Trace that request through the relevant frontend and API entry points; done means refreshing the page no longer cancels the running task, with a regression test if an applicable test location is found.
