Comment:

 Thank you, @SergeyBiryukov, for your consideration of this ticket for a
 5.7.1 release.

 I added a patch with changes that should solve the problem. I'm happy to
 adjust and provide a new one if there is any feedback.

 I'm also increasing the severity of this issue to **critical** because we
 have observed that downgrading to the previous WordPress version (5.6.2)
 will only fix subsequently uploaded images. In testing, images uploaded
 while 5.7 was the active version are not retroactively updated after the
 downgrade. I believe this is because the height, width, and additional
 attachment metadata are written to the database on upload.

 It is worth noting that the patch I provided also does not retroactively
 repair missing metadata for any affected images.
