Download button download scaled image instead of original one

[civita]

Hello, I use Fancybox in Wordpress, and found that the href to the download button changed from original image (no suffix) to the resized image (xxx-2048x2048.jpg for example) after any button (left, right, share, etc.) is clicked. The size of image is based on the width of the browser. The link should not be replaced. The reason might be that current.opts.image.src or current.src is not updated to the original image after other button is clicked.

This issue can be reproduced by clicking any button with narrow width window and then click download button.

If more information regrading this is needed, please let me know.
