The Status is not displayed for Pages, only for the whole Book

After you create a new book, it's default Status is "—" which makes the Status for the book, as well as each Page of the book be displayed as empty / blank.

If you change the Status of the Book to "Draft" / "Review" / "Complete", this change in Status will be displayed for the Book, but not for the individual Pages. These will still have the same empty / blank Status displayed.

I've tried downgrading BV to previous versions, and I encountered the same behavior.

Edit:
I tested using BV 1.26 and reproduced on 16.10.9 and 16.10.8. I did not try other versions as well.
I also tried version 1.26 of BV on XWiki version 16.4.6, and on this version of XWiki, the Status works correctly. I'm able to set a Status for the Book, as well as for each individual Page of the Book.
