JSON text format does not work when text commands (/title, /tellraw) are ran.

If you input json into a command block or in the chat via a command, for example:

/title @a title

{"text":"GAME OVER",color:dark_red,bold:true}

The game will send the output as follows:

[18:39:54] Invalid json: malformed JSON at line 1 column 1

I am aware this is a repeat of an older report, but it'd be nice to have working json strings and text commands.
