Comment:

 I did some testing and this is still present today in 6.0.x.

 [attachment:"26381.diff"] disables the scale button when the entered
 dimensions would result in upscaling. But it feels confusing not to
 present more information to the user.

 Additionally, I think that `wp_save_image()` (which is the function called
 for `scale` AJAX requests) could probably be updated to return an error
 when attempting to enlarge an image. I'll upload a separate patch that
 includes that change, but this may cause some problems in other locations,
 so may need more testing.
