An anime trailer could play before live-action content: the genre filter
accepts any single shared genre (anime is tagged Animation + Drama/Action/...),
and when nothing matched it fell back to the whole pool. Trailers tagged
Animation or Anime are now dropped for non-animated features before the
filters and the fallback run, so a live-action feature gets no trailer
rather than an animated one.
