#64518: Interactivity API: `data-wp-bind` stops processing valid directives when
encountering an invalid one

-------------------------------+--------------------
 When the Interactivity API is processing the `data-wp-bind` directive on
 the server using the `data_wp_bind_processor` method,
 [https://github.com/WordPress/wordpress-
 develop/blob/bee33568389cc8dc534fc4c19f1488ded1059386/src/wp-includes
 /interactivity-api/class-wp-interactivity-api.php#L1029 a `return`
 statement inside a `foreach` loop] causes the function to exit entirely
 when encountering a `data-wp-bind` directive with an empty suffix or a
 unique ID. This prevents any subsequent valid bind directives on the same
 element from being processed.

 Steps to Reproduce:

 1. Create an element with both an invalid `data-wp-bind` directive (no
 suffix) and a valid one:


 {{{
 <div
   data-wp-interactive="myPlugin"
   data-wp-context='{"id":"some-id"}'
   data-wp-bind="context.id"
   data-wp-bind--id="context.id"
 >
   Text
 </div>
 }}}

 2. Process the directives using `wp_interactivity_process_directives()`.

 Expected Behavior:

 The invalid `data-wp-bind` (no suffix) should be skipped, and the valid
 `data-wp-bind--id` should be processed, resulting in:

 {{{
 <div
   data-wp-interactive="myPlugin"
   data-wp-context='{"id":"some-id"}'
   data-wp-bind="context.id"
   data-wp-bind--id="context.id"
   id="some-id"
 >
   Text
 </div>
 }}}

 Actual Behavior:

 The `return` statement exits the function when it encounters the invalid
 directive, so the valid `data-wp-bind--id` is never processed. The `id`
 attribute is not added.
