Standardized API to set unique IDs in directives
HTML does not allow multiple attributes with the same name on a single element, yet multiple plugins may need to add directives of the same type to the same element. To address this, WordPress 6.9 introduces a standardized way to assign unique IDs to Interactivity API directives, allowing an element to have multiple directives of the same type, as long as each directive has a different ID.
