Any selection (if not carefully made sure is aligned to jpg block sizes) that is used for the losseless crop feature, in most cases ends with a cropped image that have a final size that is slightly off compared to size of original selection, aka wanted size.
It would be very useful if there was an options that - when jpg losseless crop is used - automatically adjustment of selection is performed so that the final size of cropped image perfectly matches the size of selection
