Hi Mike. What I was doing is exactly the same as yo did. I tested on multiple machines and found something strange.
When the volume size is default with no change to the localrc file, the snapshot can be deleted successfully; when the volume size is set to a different value like VOLUME_BACKING_FILE_SIZE=25G in localrc, this issue will be raised and the status of the snapshot gets stuck to "deleting".

When command cinder snapshot-delete is called, the following log prompts:
