Local Pickup: the Save changes button redirect to a blank page in Firefox browser

[tarhi-saad]

Describe the bug

In the Local Pickup admin page, clicking on the Save changes will redirect to a blank (i.e., /wp-admin/admin.php?local_pickup_title=Local+Pickup). The changes will be saved, but the merchant must go back to the previous URL and refresh the page to see the changes!

To reproduce

Steps to reproduce the behavior:

You should use the Firefox browser for this test.

1. Go to WooCommerce/Shipping/Local pickup
2. Click on the Save changes button. You'll be redirect to a blank page (/wp-admin/admin.php?local_pickup_title=Local+Pickup)

Expected behavior

Clicking on Save changes shouldn't redirect to another page. Check the expected behavior using another browser (e.g., Chrome):
