What happened in your environment?

I want to

1. push an artifact to localhost:5000/test with tag v1.1
2. tag the pushed artifact with latest and v1

$ oras push localhost:5000/test:v1.1,v1,latest --format {{.Ref}} --no-tty 
Tagged latest
Tagged v1
localhost:5000/test@sha256:0e0e404fe40f2409b1964272434fbe3b9293f262fd62f90ab9df49d54579818e

The output contains both tagging log and digest reference of pushed artifact.

What did you expect to happen?

The output should only contain digest reference of pushed artifact.

$ oras push localhost:5000/test:v1.1,v1,latest --format {{.Ref}} --no-tty 
localhost:5000/test@sha256:0e0e404fe40f2409b1964272434fbe3b9293f262fd62f90ab9df49d54579818e
