Ajax driven Views exposed Forms do not get 'data-bef-auto-submit-exclude' set via JS

Problem/Motivation

When delivering/updating Exposed Forms for views, Drupal.behaviors.autosubmitExcludeTextfield fails to set again the 'data-bef-auto-submit-exclude' if present.

Steps to reproduce

If the a Views exposed form is refreshed/updated via Ajax the once() code in will fail.
Because Drupal (as of 10.4) still does not provide this functionality as part of core, testing this patch (or a similar approach) might help
https://www.drupal.org/files/issues/2025-02-26/drupal-exposed_forms_in_b... →
The reason for that is because the once() runs over a context that has as a child the '.bef-exposed-form', but ignores if the the actual context has that class, which is what happens with an Ajax driven reload of an exposed form is executed, the context == form.

Proposed resolution

There are two ways of approaching this:

This one requires that the returned form (context) has actually changed its #id (which is not the case for the demo patch shared), but even so, it will not fail (will (once) twice, the wrapper and the child

**
   * Adds the data-bef-auto-submit-exclude to elements with type="text".
   */
  Drupal.behaviors.autosubmitExcludeTextfield = {
    attach: function (context, settings) {
      if (!settings.better_exposed_filters?.autosubmit_exclude_textfield) {
        return;
      }
      let elementsToAttach = [];
      if (context !== document && context.classList.contains('bef-exposed-form')) {
        elementsToAttach = once('autosubmit-exclude-textfield', context);
      }
      else {
        elementsToAttach = once('autosubmit-exclude-textfield', '.bef-exposed-form', context);
      }

      $(elementsToAttach).each(function () {
        $(this).find('*[type="text"]').attr('data-bef-auto-submit-exclude', '');
      });
    }
  };

This other option is even simpler. If what changed is the actual Form, then `onceing` it really makes no sense, just setting the value is enough.

  Drupal.behaviors.autosubmitExcludeTextfield = {
    attach: function (context, settings) {
      if (!settings.better_exposed_filters?.autosubmit_exclude_textfield) {
        return;
      }
      let elementsToAttach = [];
      if (context !== document && context.classList.contains('bef-exposed-form')) {
        elementsToAttach = context;
      }
      else {
        elementsToAttach = once('autosubmit-exclude-textfield', '.bef-exposed-form', context);
      }

      $(elementsToAttach).each(function () {
        $(this).find('*[type="text"]').attr('data-bef-auto-submit-exclude', '');
      });
    }
  };

What none of this code really does is to allow mixed cases to exist: One Exposed form with and another one without text field exclusion, one a first page load, this code will unify their settings. It takes settings.better_exposed_filters?.autosubmit_exclude_textfield as global, which means on a first load (context === document) either all/or non text fields inside a .bef-exposed-form will get this data attribute.

Which is unclear to me why, if there are already values for the other options
```
data-bef-auto-submit-full-form = ""
data-bef-auto-submit = ""
data-bef-auto-submit-delay = {int} 500
data-bef-auto-submit-minimum-length = {int} 3
```

there is no `data-bef-auto-submit-exclude` set at the Render array level instead?

Remaining tasks

Wait for the maintainers to confirm which of the 2 approaches is better

User interface changes

None

API changes

None

Data model changes

None

Thanks a lot
