 When registering a piece of meta as a nullable type in the REST schema, it
 does not display in the JSON schema for the particular object.

 For example, the following will not correctly register a meta key in REST:

 {{{#!php
 <?php
 register_meta(
         'post',
         'backgroundColor',
         [
                 'single'       => true,
                 'type'         => 'string',
                 'show_in_rest' => [
                         'schema' => [
                                 'title'  => __( 'Background Color' ),
                                 'type'   => [ 'string', 'null' ],
                                 'format' => 'hex-color',
                         ],
                 ],
         ],
 );
 }}}

 The key will not be visible in the JSON schema, and the key/value pair
 will also not be available in the meta object in the post response from
 the API.
