Assistants are unaffected by rescaling the image, and so they will be incorrect after rescale. Steps to repo: 1; Create an image 2; Place assistants and specific points 3; Rescale image to 50% width and height. Actual behavior: Assistants retain their position relative to the original image size. Expected behavior: Assistants retain position and scale relative to the image's new dimensions.
This happens for Canvas Resize and Offset Image and Trim operations. Anything that shifts the image coordinates with respect to the top left corner. The assistants have an X/Y offset definition that is not altered/compensated when these operatuions are done.
