 According to the inline documentation of `WP_Block_Parser`, `parse_blocks`
 should return ''arrays not objects, all attributes are arrays''. See
 https://core.trac.wordpress.org/browser/branches/5.0/src/wp-includes
 /class-wp-block-parser.php#L124

 Parsing
 {{{
 <!-- wp:paragraph -->
 <p>First paragraph</p>
 <!-- /wp:paragraph -->
 }}}

 returns

 {{{
 Array
 (
     [0] => Array
         (
             [blockName] => core/paragraph
             [attrs] => stdClass Object
                 (
                 )

             [innerBlocks] => Array
                 (
                 )

             [innerHTML] =>
 <p>First paragraph</p>

         )

 )
 }}}

 If the block has no attribute, `[attrs]` is an empty object while,
 according to the documentation, we would expect an empty array.

 In other cases, when the block includes attributes or when parsing a free
 form text, `[attrs]` is, as expected, an array.
