From version 2.9.11 and on, Elementor will use the use wp_allowed_protocols() function to handle allowed URI protocols in links. These protocols are often used to create a deep-link (i.e. a direct link to an app via unique protocol) to a 3rd party application (such as mailto: or tel:)
If you add a custom link or a dynamic link (in any URL field) with a URI protocol that is not supported by WordPress such as waze:// etc., it will no longer work.
