Environment info
These error messages are new and started appearing after updating to 21.8.0 and have not been fixed by updating to the latest version of Gutenberg (21.8.2), or by uninstalling then reinstalling Gutenberg. I am running the Livro theme with the following plugins:

The conflict seems to be with WooCommerce, as when I deactivate all plugins except for Gutenberg, then re-enable WooCommerce, the following error messages flash up at the top of the HTML code though they are not visible after the page has fully loaded:

<!DOCTYPE html>
After also activating the woocommerce-square plugin (or any plugin dependent on woocommerce), the error messages become visible on the site.
Deactivate gutenberg gets rid of the error message but then results in a The installed theme requires [Gutenberg](https://wordpress.org/plugins/gutenberg/) version 12.8 or higher. error message throughout the admin backend. The front end and most of the site seems to display and function fine without gutenberg activated but it'd be better if the bug got fixed.
