SNBT removing spaces from string in command

When I try to give me in Minecraft a book with a custom text with multiple spaces in a row they will be cut down to a single space.

Steps to reproduce:
1. Enter following command to get the book: /give @p written_book[written_book_content={pages:[["",{text:" Multiple Spaces to the left"}]], title:"My Spaces :(", author: "Player"}]
2. Open the Book

Expected Result:
The Book has the content “ Multiple Spaces to the left”.

Observed Result:
The Book has the content “ Multiple Spaces to the left”.

When you try to get the command back to the chat line with the arrow keys the spaces in the command are also removed.
The restored command is /give @p written_book[written_book_content={pages:[["",{text:" Multiple Spaces to the left"}]], title:"My Spaces :(", author: "Player"}] instead of /give @p written_book[written_book_content={pages:[["",{text:" Multiple Spaces to the left"}]], title:"My Spaces :(", author: "Player"}].
