'Team' nbt not working in minecraft servers

The 'Team' nbt in /summon command doesn't not actually currently work on Minecraft servers. I'm unsure if it works on LAN port multiplayer system based server because it's basically joining a single player world, but Minecraft servers do not work.

What I expected to happen was...:
/summon <entity> ~ ~ ~ {Team:"<team>"}

The command should run properly and join the selected entity in to a team.

What actually happened was...:

I tried to use the /summon <entity> ~ ~ ~ {Team:"<team>"} command on a Minecraft server, because I thought it would just work like I've done in single players. I knew that teams on entities does not affect friendly fire settings in multiplayers, but I didn't think this team nbt would not work on Minecraft servers.

 

Steps to Reproduce:
1. Open a Minecraft server.
2. Add a team.
3. Type /summon <entity> ~ ~ ~ {Team:"<team>"}

4. Voila~! Doesn't work
