Load Image node when you edit it with the mask editor no longer saves the image WITH metadata on ComfyUI\input\clipspace

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have searched existing issues to make sure this isn't a duplicate
- [x] I have tested with all custom nodes disabled ([see how](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled))

### What happened?

This used to work, the images after being edited with the mask editor would be saved on the clipspace WITH metadata (positive prompt, negative prompt etc). Now it doesn't.
Why this is important? On my inpainting workflow I used to automatically get the image path on run, to show the image metadata for the "SD Prompt Reader" node and get the original image positive prompt.

### Steps to Reproduce

1. Load a image with metadata
2. Edit the image with metadata with mask editor, click on save
3. Open the windows explorer `\ComfyUI\input\clipspace` check the image there, it won't have metadata
