The <Pill> component that is used on a number of pages is implemented with a <button>: https://github.com/metabrainz/listenbrainz-server/blob/3335087660314fdd4c92c888bed308981085e75a/listenbrainz/webserver/static/js/src/stats/UserEntityChart.tsx#L409-L430

This means that it can't be used to link to a new page/tab, or show the URL in the browser status bar (LB-864, LB-925).

I think that these should be changed to <a> to make them act like regular links.
