--untagged command does not indicate to delete matchings manifests
When using the acr purge command, adding '--untagged' does not tell the purge to delete images that match the filtered tag. It only tells the purge command to delete images that no longer are tagged.
I'm trying to purge images by tag, but some images have multiple tags. Adding the --untagged command doesn't help me at all. Instead only the matching tags are removed from the images.
