Written Book Raw JSON Bug With Cheats Off

I expected this command:

give @p written_book 1 0 {title:"Stats",author:"Architect",pages:["{\"text\":\"Times Won: \",\"color\":\"dark_green\",\"extra\":[{\"score\":{\"name\":\"@p\",\"objective\":\"Wins\"}},{\"text\":\" Times Lost: \",\"color\":\"red\",\"extra\":[{\"score\":{\"name\":\"@p\",\"objective\":\"Losses\"}}]}]}"]}

to display the holder's scores for Wins and Losses, without Cheats being enabled.

However, when I hold this book it displays this text:"{text:'Times Won: ',color:'dark_green',extra:[{score:{name:'@p',objective:'Wins'}},{text:' Times Lost: ',color:'red',extra:[{score:{name:'@p',objective:'Losses'}}]}]}", this only occurs when Cheats are off, when Cheats are on, it does exactly what it should.

Steps to Reproduce:
1.Start a Creative World With Cheats
2.Give Yourself a Written Book With Any Form of Raw JSON Coding.
3.Edit The World to Disable Cheats
4.The Book Will Fail to Execute The Coding, Displaying The Code Itself In It's Place
