Description

Since upscaler progressbar appeared, I've noticed image is upscaled two times for inpainting if upscaler_for_img2img is overridden. I debugged with console log, and Image.show(), they are exactly the same images and exactly the same target resolution. It happens because of saving original_denoised_image outside apply_overlay function

Reproduce:

1. Override upscaler for img2img
2. Inpaint area = Only masked
3. Inpaint area that bigger then 512x512 in 512x512 resolution
4. See in console two upscales
