Trying to type /tellraw @s {text: "\u000f0000a"} in chat crashes the client

When typing the following command in chat:

/tellraw @s {text: "\u000f0000a"}

the game crashes after inputting the “a” character in “\u000f0000a"

If you manage to successfully enter the command (for example by first typing /tellraw @s {text: "\u000f000a"}, and then going back with your cursor and adding another 0, using the Up arrow key to re-type the command crashes the game as well.

This also happens when pasting the command.

It seems like the issue lies in the syntax hints that appear above the command. They are supposed to appear when the cursor is placed after the \u000f000a part, but something is broken and they crash the game instead.
