Camera Raw: Saved Super Resolution DNG embedded preview is not sized correctly
I converted a raw file DSC_0042.NEF to a Super Resolution DNG using ACR 13.2. This created a file called DSC_0042-Enhanced.dng. Before exiting ACR, I chose to Save the new file as well (right-click Save Image->Save Image...), selecting the DNG format, Camera Raw 12.4 and later Compatibility, Medium Size JPEG Preview and Embed Fast Load Data. This created a file called DSC_0042-Enhanced_1.DNG.
After exiting ACR, I imported the original NEF and the two Super Resolution DNGs into Lightroom Classic 10.2 with Embedded & Sidecar Preview option set.
Here is a shot of the images in the LrC's Library Grid view.
Notice the preview of DSC_0042-Enhanced_1.DNG. It is not sized correctly, showing only the (large) top left corner of the image. The preview of the DSC_0042-Enhanced.dng is sized correctly, showing the full image.
Looks like a bug in ACR's Save Image option.
