Bugs
1. You shouldn't be able to teleport to yourself (that's why you can't use "Teleport to player" when you are the only player in the world)
2. The menu should close after teleporting (what it doesn't do right now, it stays open with no option exept "9" (Close))

How do you know?
As of right now, you are able to teleport to yourself.
As for the second "bug", it appears to be a feature request, which is NOT accepted here! Please go here: http://www.reddit.com/r/MinecraftSuggestions

Blah what do you have against my issue reports?
I think it is not intended that after selecting a player to teleport to stays empty!
And because it is a WIP it needs support from the players who report BUGS!
That is the reason for this bug tracker, to make fixing bugs easier for the MOJANG team!
As of right now, you are able to teleport to yourself. The menu is currently a WIP.
This is exactly what the bug describes. That the menu is WIP would only explain why the bug exists, not that it would be intended.
As for the second "bug", it appears to be a feature request, [...]
Have you even done what the description tells you? You just get an empty menu with just the option to close it after the teleportation. Seems more like a bug to me that like an intended thing and even if it was intended it seems reasonable to report it as a bug without the need for you to tell the reporter that he's doing things wrong and making feature requests.
Also, I'd recommend you to write more than just "Intended."
Even the Moderators write something like "Works as intended."
Also, you are not Mojang, so all you could argue would be "Probably works as intended.", or "Works as intended, see ..." with a link to some information from Mojang that proofs their intentions.
Frank Steffahn, sorry to say this, but that is considered bullying. Please stop.

Blah it is not bullying but Frank Steffahn is right I guess, just see it as suggestion 🙂

@@unknown: @unknown is not bullying you (but accusing him of doing so could be considered as....).
People are simply annoyed of your unsourced, arbitrary Intended
. Take the recommendation of @unknown as positive criticism.
I'm sorry If you feel bad from my comment, I really just wanted to help you with some tips / suggestion.
Is this still an issue in the latest snapshot 16w44a? If so please update the affected versions.
This is an automated comment on any open or reopened issue with out-of-date affected versions.

Can confirm in 1.13-pre3.
Just to add, I don't see my player skin, just the default, and no name is shown when I hover over it. Probably not intended.
Confirmed for 1.13.1.Â
Please, update the commands in the description:
/team add Hi
/team join Hi

You can alo teleport to yourself with commands!
/teleport @s @s

You cannot teleport to yourself, and you never have been able to. After choosing "Teleport to Team Member", you are asked to choose a team. Upon selecting your own team, a list of players on your team is displayed, excluding yourself. This is why the menu doesn't close (since if you're the only player on the team, then the list is empty).
Confirmed.
