Comment (by birgire):

 Welcome to trac and thanks for the ticket.

 We can reproduce this with:

 {{{
 // output: {"0":"post","2":"page"}
 $json = wp_json_encode( array( 0 => 'post', 2 => 'page' ) );

 // output: ["post","page"]
 $json = wp_json_encode( array( 0 => 'post', 1 => 'page' ) );

 }}}

 where  {{{wp_json_encode()}}} is a wrapper of {{{json_encode()}}}.

 This seems to be an expected behavior for {{{json_encode()}}}.

 So you're suggesting to re-index it, to ensure the array output?
