Same images are being provided when trying to upload multiple images

When trying to upload multiple images the saveImage method returns the first image all the times. Here is a reproducible sandbox with v11.5.0 for it:

To reproduce:

• Try uploading multiple images in the sandbox above
• Check the logs, to see the same image is logged for all cases

Unfortunately. I have almost no time to work on this library and I will be focusing on version 12 now, and it still doesn't support file uploads.

I quickly looked at your problem and it seems that, at least by uploading from the clipboard, the File objects seem to have different sizes. The preview is obviously the same because we are always yielding https://picsum.photos/300
