I created a tag using the BitBucket web UI.
The tag can be seen here: https://bitbucket.org/njlr/hello-buckaroo/commits/tag/v0.1.0
As you can see, the tag should point to commit 4ead5911c2d85e06873eecd0dff6229ada3e101c.
However, we I query the tags in the Git CLI, there seems to be an extra tag:
git ls-remote --tags git@bitbucket.org:njlr/hello-buckaroo.git
5339ed577895ffd2c8e4aac683efec9f855d5c91 refs/tags/v0.1.0
4ead5911c2d85e06873eecd0dff6229ada3e101c refs/tags/v0.1.0^{}
Where did 5339ed577895ffd2c8e4aac683efec9f855d5c91 come from? Why did BitBucket create this?
