If you have a custom workflow event that returns eZWorkflowType::STATUS_REDIRECT, the status won't be correctly set and the items will disappear from admin interface because of that.

Steps to Reproduce

1. Create a custom workflow event according to the following code

   class myTest extends eZWorkflowEventType
   {
       const WORKFLOW_TYPE_STRING = 'mytest';
       function __construct(){
           parent::__construct(self::WORKFLOW_TYPE_STRING, 'My Test');
       }
   
       function execute( $process, $event ){
           $process->RedirectUrl = '/';
           return eZWorkflowType::STATUS_REDIRECT_REPEAT;
       }
   }
   
   eZWorkflowEventType::registerEventType( myTest::WORKFLOW_TYPE_STRING, 'myTest' );
   

2. Create a new workflow and set it to before\publish trigger
3. Create a new article
4. The item won't be displayed at pending items

Note: This was working in all versions before eZP 5.2
