I didn't notice it until now, but it looks like there's a regression on beta where a "Search for an artist:" text label is displayed directly above the artist autocomplete inputs on the release and release group forms (and probably others).

bitmap, from looking at the commit history, I think this might be a CSS specificity issue introduced by https://github.com/metabrainz/musicbrainz-server/pull/3420.

#ac-source-single-artist-label is still getting matched by this:

label.autocomplete2-label {
    display: none;
}

but the display: none is being overridden by this:

table.row-form label {
    display: inline-block;
    text-align: right;
}
