 Currently, WP_Theme_JSON sanitization is not able to sanitize data
 contained on indexed arrays. So certain data from theme.json, for example,
 settings.typography.fontFamilies which is a JSON array, cannot be
 sanitized. Why? because when parsing the JSON data WP_Theme_JSON
 translates JSON arrays into PHP indexed arrays and the class is not
 capable of sanitizing that kind of data.

 I think it would be useful to add nested indexed array schema sanitization
 capabilities to the WP_Theme_JSON class. For that reason, this ticket is
 aimed to bring that capability into core from WP_Theme_JSON_Gutenberg.
