Can't see EBS Snapshot tags from other accounts

Hi,

I have private snapshots in one account (source) that I have shared with another account (target). I am able to see the snapshots themselves from the target account, but the tags are not available, neither on the console nor via the cli.
This makes it impossible to filter for a desired snapshot from the target account.
For background, the user in the target account has the following policy in effect:

            "Effect": "Allow",
            "Action": "ec2:*",
            "Resource": "*"

Here's an example of what I'm seeing; from the source account:

$ aws --region us-east-2 ec2 describe-snapshots --snapshot-ids snap-XXXXX
{
    "Snapshots": [
        {
            "Description": "snapshot for testing",
            "VolumeSize": 50,
            "Tags": [
                {
                    "Value": "test-snapshot",
                    "Key": "Name"
                }
            ],
            "Encrypted": true,
            "VolumeId": "vol-XXXXX",
            "State": "completed",
            "KmsKeyId": "arn:aws:kms:us-east-2:XXXXX:key/mrk-XXXXX",
            "StartTime": "2022-04-19T18:29:36.069Z",
            "Progress": "100%",
            "OwnerId": "XXXXX",
            "SnapshotId": "snap-XXXXX"
        }
    ]
}

but from the target account

$ aws --region us-east-2 ec2 describe-snapshots --owner-ids 012345678900 --snapshot-ids snap-11111111111111111
{
    "Snapshots": [
        {
            "Description": "snapshot for testing",
            "VolumeSize": 50,
            "Encrypted": true,
            "VolumeId": "vol-22222222222222222",
            "State": "completed",
            "KmsKeyId": "arn:aws:kms:us-east-2:012345678900:key/mrk-00000000000000000000000000000000",
            "StartTime": "2022-04-19T18:29:36.069Z",
            "Progress": "100%",
            "OwnerId": "012345678900",
            "SnapshotId": "snap-11111111111111111"
        }
    ]
}

Any ideas on what's going on here?

Cheers!
