A long-lasting bug that might never be fixed

So, there is a bug that hasn't been patched for a while. This bug happens like so and applies to most devices and connections.

It basically gives the player no name. But what's weirder is the command syntax for teleporting these no-name players and other commands add these quotations with no text inside them.

And when they talk in chat, it looks like a /tellraw message even when they don't have permissions or hack clients. Basically, without the <>.

hi

I have no idea why this happens. I have tested this on several devices and I have concluded that on a bad connection, it happens 70% of the time. On an OK connection, it happens 65% of the time. On a good connection, it happens 60% of the time. On an extremely good connection, it happens 40% of the time. When the connection is extremely slow or a little bit slow, it happens 80% of the time. This likes to happen to players that don't have Xbox Live or are using a LAN Connection to play the game such as Omlet Arcade or other 3rd party applications.
