 WordPress version: 5.6
 WooCommerce version: 4.8.0

 On the 5.6 version of WordPress, leaving a page with classic editor will
 prompt the users with a confirmation dialog. It's not happening on the
 previous version of WordPress.

 Steps to reproduce:
 - On a clean WordPress installation
 - Install and active WooCommerce plugin
 - Create a product and publish it
 - Edit the product
 - Exit the page without doing any changes

 Not sure if it's related to WooCommerce only or a bug in core instead,
 because it's not happening in my other site with WordPress 5.4.2 and the
 same version of WooCommerce.

 I'm able to pin-point the line that causes this error:
 https://core.trac.wordpress.org/browser/tags/5.6/src/js/_enqueues/vendor/jquery/jquery.js#L5601

 Seems like has something to do with the recent jQuery update.
