Comment (by abitofmind):

 Note: This issue here avoided to create responsive images that are larger
 in file size than their original by avoiding to create lossless responsive
 images from lossy originals.

 Now as extreme as this may seem but in #57238 there's one case where the
 reverse is happening! The first 2 next smaller sized versions in the
 responsive images set are lossy (!) but nevertheless larger in file size
 than their larger original which is lossless and with an alpha channel.
 Only the 3rd responsive image is then smaller in file size than the
 original. Check it out!
