In https://listenbrainz.org/settings/missing-data/ I had a release where a lot of tracks didn't get matched properly at the release level and I needed to match track by track. As soon as the release got to have less unmatched tracks than the next one in the list, it will slide down the page, eventually moving pages entirely - with one track left, I cannot even find it anymore. That's... not ideal - it makes sense to sort like this on page load, but please consider keeping the order after that (or pinning the last release matched on top or something at least).
