Self-Attention Guidance seems to cause memory leak or break down image inference

### Expected Behavior

Makes image.

### Actual Behavior

Doesnt make image, black screen, image disolves during inference into blue and yellow noise and next frame is black.

### Steps to Reproduce

Simple setup, some PONY checkpoint, clip skip -2, some simple prompt, SAG node at 0.25 and 1.00, typical denoise via DPM++ 2M and Karras around 30 steps.

Current version of ComfyUI - 0.3.26 doesnt say anything in console, but 0.3.24 did mention something about SDXL memory leak or something due model circle referenced something (didnt save it).

SAG node is always bit problematic to say at least, but apart combination with certain nodes that modifies similar stuff, it worked.
