Branch env variables on tag events

Hi, just for clarification:

As the documentation is mentioning for all branch environment variables (e.g. https://docs.drone.io/pipeline/environment/reference/drone-branch/) “[…] may be empty for tag events.”, under which circumstances are these variables filled for pipeline events of type “tag”?

I recognized the branch variables are always given on tag events with the same value of DRONE_TAG.
