[Bug] Audio workflow Tuple index out of range during decode tiled

### Expected Behavior

The VAEDecode node was decoding while I was using AceStep to generate music

### Actual Behavior

An error occurred. However, while using the workflow, it only happens every once in a while (not consistent error).

```
File "/home/c_byrne/projects/comfy-testing-environment/ComfyUI/comfy/utils.py", line 959, in tiled_scale_multidim
if feather >= mask.shape[d]:
~~~~~~~~~~^^^
IndexError: tuple index out of range
```

### Steps to Reproduce

Reproduce with this workflow:

[tuple-index-out-of-range.json](https://github.com/user-attachments/files/20086346/tuple-index-out-of-range.json)
