On https://musicbrainz.org/release-group/3bd76d40-7f0e-36b7-9348-91a33afee20e/tags there is:
"Tags with a score of zero or below, and tags that you’ve downvoted are hidden.
Show all tags."
I would expect to have the equivalent option after showing all tags:
"All tags are being shown.
Hide tags with a score of zero or below, and tags that you’ve downvoted."
