Img2Img Denoising is broken, setting it to 1 (full) still impacts the sampling

Setting denoise to 1 will still show influence of the input image:


Expected behavior: Denoising 1.0 should fully denoise the input and thus the image should have zero impact on the sampling. However, it apparently does not get fully denoised. The output is still influenced by the image instead of giving the same result as passing an empty latent image.
