 Right now, WordPress does not allow double hyphens `--` inside data
 attributes.

 https://github.com/WordPress/wordpress-
 develop/blob/16237a11586b022861933fa738acd957eef6653e/src/wp-
 includes/kses.php#L1267

 That's a problem for Interactivity API directives like `data-wp-on--event`
 or `data-wp-bind--value`.

 Right now, all PHP with those directives parsed with this function, will
 not be rendered, stopping all kind of interactions.

 Because of that, static blocks are not supported yet(as they are saved in
 DB, and pass through a wp_kses before sending them to the browser).

 Some plugins are starting to notice the issue, like WooCommerce:
 https://github.com/woocommerce/woocommerce/issues/46722

 Can this function be updated to allow them?

 Is there any concern or edge case I could miss before creating a PR?
