[Issue]: Inpaint sketch resizing image on canvas without being prompted

[mark-wd]

Issue Description

Following from #860

Updated to the latest build and the problem persists.

Digging deeper, I've found that this behavior happens during the following workflow:

• Generate a 512wX768h image in txt2img, my batch count was 4.
• Choose one of the images and click the "->IMAGE" button below to send to img2img
• On the img2img tab, click the "Inpaint sketch" button below the canvas
• At this point, computer resource usage spikes way up. The resulting image on the canvas is actually resized to be way bigger
• Browser slows down massively and any further work is halted due to the size of the image. If it manages to be processed, it results in DecompressionBombError.

Behavior seen on Win11/Firefox
