Tag created after deletion of previous tag with the same name will always have the same release notes

Summary

If I create a tag and then remove it and then re-create a tag with the same name then newly entered release notes won't be used; release notes from the first tag with this name ever created are always shown.

Steps to reproduce

1. Create a tag specifying release notes
2. Delete this tag
3. Create a new tag with the same name but different release notes
4. (old release notes can be seen instead of new)
