Gen 5 animated sprites don't appear in the online client

This PR works for me locally, but the animated sprites are not being rendered on the prod client.
The left side shows the online client and the right side shows the client running locally (only the right side is animated).
This is only referring to the opponent Pokémon — the local client animates them correctly, but the production client does not.

The animated sprites appear in replays (see Gholdengo here):
