ACR Update DNG preview not working after Export Settings to XMP

When using ACR image menu and selecting Export Settings to XMP then closing image with Done button DNG preview is not being updated. ACR only updates preview if any change happens, after Export Settings to XMP being used.

Sometimes i do a lot of Export Settings to XMP as precaution because ACR crash frequently and i might loose all the progress i made and if i don’t remember to use Export Settings to XMP then preview never updates. 

Please fix to update preview after Export Settings to XMP being used.
