Cart route being loaded in editor

[kimmenbert]

Describe the bug

Even without any WooCommerce blocks in content, the speed of the editor seems to be affected by WooCommerce blocks.
On a project I'm working on, I hooked into woocommerce_check_cart_items. I never expected that using that filter would be triggered back-end.

This makes me wonder. How much non-needed logic is processed in the editor. Worst case, will editor performance now be affected by the number of products in your cart session?

To reproduce

1. Log in to admin, go to the edit screen of any page / post

2. Add this piece of code to your functions.php / a custom plugin

function thing_happens_in_editor() {
  die( 'Why' );
}
add_action( 'woocommerce_check_cart_items', 'thing_happens_in_editor', 1 );

3. Reload page, see "Why" message

Expected behavior

I would not expect this logic to affect the editor, at least not when the editor does not even contain any WC block

Environment

WordPress (please complete the following information):

• WordPress version: 6.1.1
• WooCommerce version: 7.3.0

Thank you for letting us know @kimmenbert! Cart session should not be reached during render in the editor, we use a fully mocked up cart to avoid that, there may be a regression that caused this. I will reword the issue title to reflect that.

Triggered by the "All Products" block for some reason. Investigating.
