Extras tab keep upscaling the old image when using copy/paste, also, right clic copy the resulting image doesn't work

[Mozoloa]

Describe the bug
In the extras tab, if you paste an image to upscale it, then paste another one (seems to be especially if the size is the same), it's gonna keep upscaling the first one

Also copying the upscaled image doesn't work anymore, nothing goes into the clipboard

To Reproduce
Paste an image to upscale it in the extras tap, upscale it, then remove the previous one & paste another one (seems to be especially if the size is the same), it's gonna re upscale the first one. In the same time try to copy the upscaled image it doesn't work either.

Expected behavior
Should upscale the new one and right click copy should work

I can reproduce substantially the same bug with this procedure:

1. Make anything with txt2img and send it to inpainting.
2. Inpaint it with batch size > 1.
3. Pick any of the inpainting outputs and send it to extras.
4. Upscale.
5. Pick a different inpainting output and send it to extras.
6. Try to upscale that. It'll output the same image as you got in step 4, and if you use LDSR, it'll do so much faster than is normally possible (implying it's pulling from some kind of cache that needs to be invalidated).
