 When changes are made to `$parsed_block['innerContent']` using the
 'render_block_data' filter, those changes are only applied to top-level
 blocks, not to inner blocks.

 The issue is how we deal with inner blocks in `class WP_Block`'s render
 method: we don't create a new instance between applying the filter and
 calling render on the inner block[https://github.com/WordPress/wordpress-
 develop/blob/trunk/src/wp-includes/class-wp-block.php#L241], so changes to
 `innerContent` aren't actually applied.

 Ideally we should apply the same logic here as we do in the `render_block`
 function: [https://github.com/WordPress/wordpress-develop/blob/trunk/src
 /wp-includes/blocks.php#L903].
