Incompatibilities with search_api

Problem/Motivation

On Drupal 11, because of some cache unserialization done by search_api, ViewsBulkOperationsBulkForm is instantiated twice, and so the ViewsBulkOperationsViewData service is initialized twice too. First with the valid original view, and then with the view unserialized from cache.

Sadly, the unserialized view is always empty for some reason, so it totally breaks VBO as it uses both objects simultaneously in the viewsForm method below:

    // Only add the bulk form options and buttons if
    // there are results and any actions are available.
    $action_options = $this->getBulkOptions();
    if (!empty($this->view->result) && !empty($action_options)) {

      // Get bulk form keys and entity labels for all rows.
      $entity_data = $this->viewData->getViewEntityData();

First we use $this->view->result from the original valid view object and then $this->viewData->getViewEntityData() which uses the result from the unserialized view which is always empty.

So we get in an inconsistent state that breaks VBO.

Steps to reproduce

Use VBO with search_api on Drupal 11.

Here is the code in Search API that gets the View from cache:

https://git.drupalcode.org/project/search_api/-/blob/8.x-1.x/src/Plugin/views/cache/SearchApiCachePluginTrait.php?ref_type=heads#L173

Here is the code in Views that calls initHandlers during unserialization:

https://git.drupalcode.org/project/drupal/-/blob/11.0.5/core/modules/views/src/ViewExecutable.php?ref_type=tags#L2585

Proposed resolution

Quick and dirty hack : clone the ViewsBulkOperationsViewData object so the original one is not overridden during the second init call.
