Fatal error with litespeed cache

I am getting the occasional fatal error using litespeed cache and this plugin.

It looks like liespped calls pre_kses very early and the sanitize_attributes function which is hooked to that action filter then causes the following fatal error: PHP Fatal error: Uncaught Error: Undefined constant “SECURE_AUTH_COOKIE”

This can be prevented by amending the function to instead be:

/**
 * Strips attributesForBlocks block attribute when the current user doesn't have unfiltered_html capabilities.
 *
 * @param string $content Content to filter through KSES.
 */
function sanitize_attributes($content) {
	
	if (!defined('SECURE_AUTH_COOKIE')) {
		
        require_once(ABSPATH . WPINC . '/default-constants.php');
		
    }

	if(!function_exists('wp_get_current_user')) {
		
		require ABSPATH . WPINC . '/pluggable.php';
		}
