When using lossless operations, then it should be always preserved IMO. That option is only for lossy operations.
Sorry guys, I've to check back as I guess there's a misunderstanding. Do you really want to keep the original thumbnail even if lossless crop removes 95% of the image, so
it is massively lossy but just does not re-encode the image data?? IMHO, the thumb is a small preview of the image, and if the image is changed (newly re-coded image data / lossy or not does not matter) I want the thumb to be updated so it shows the new state of the image. Elsewise I would not be able to distinguish several images in browser mode that are derived from one single image e.g. by cropping differently.
I fully agree that lossless operations like metadata editing / creating (=image is not changed) is no need for thumb re-creation.
Kind regards, Georg
