[Bug]: Queue Sidebar Image Preview Fails

### Frontend Version

v1.10.10

### Expected Behavior

The queue sidebar should display images from past generations. This should be tied to only the built-in Preview Image and Save Image nodes but for some reason it is trying to access nodes such as ShowText and other math nodes.

### Actual Behavior

The program tries (and fails) to access images from any nodes that may display an image.


### Steps to Reproduce

Any workflow that has nodes such as ShowText | pyssss or math nodes (similar to the screenshot above)

### Debug Logs

```powershell
N/A
```

### Browser Logs

N/A

### Setting JSON

N/A

### What browsers do you use to access the UI ?

Microsoft Edge

### Other Information

No file or test is named. Reproduce the issue in the queue sidebar with a workflow containing ShowText, pyssss, or math nodes, then trace the frontend code that selects images for past generations. Done means previews are limited to the built-in Preview Image and Save Image nodes without failed requests for other image-displaying nodes.
