Comment (by superdav42):

 Worth noting that WooCommerce calls `wp_script_is()` about 50 times in
 [https://github.com/woocommerce/woocommerce/blob/c78098c248eb050c8214a1309a43e954f9b3739c/includes
 /class-wc-frontend-scripts.php#L435 WC_Frontend_Scripts] so anyone running
 almost any version of WC that enqueues a script on the frontend which
 depends on wp-* will be affected by this slowdown. In WP core this is
 limited to the edit screen which only performs 1 call to `wp_script_is()`
 so the slowdown is not as noticeable.
