Your new download manager is horrible.

### 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

When I first started using Comfy, if there was a missing model, a box popped up right in front of you. This way always worked. Your new version in a side panel doesn't download. It just sits there. I have no idea if its downloading or not, nothing happens. Why did you break something that worked?

### Actual Behavior

Nothing happens.

### Steps to Reproduce

Open a Template. Click Download All. Nothing happens. Or if it does, you don't get any feedback. Clicking Refresh does nothing.

### Debug Logs

```powershell
I don'pt know what you are talking about.
```
