How does Joomla initialise all active libraries and plugins?

Question

I'm trying to import Joomla in a Yii application. It goes well, but some plugins and libraries are not loaded. Does anyone know how to achieve this? Something like

JPluginHelper::loadAllActivePlugins();

This is my code so far:

    define('_JEXEC', 1); 

    $joomlaRootFolder = \Yii::$app->params['joomlaRootFolder'];

    if (file_exists($joomlaRootFolder . '/defines.php')) {
        include_once $joomlaRootFolder . '/defines.php';
    }   

    if (!defined('_JDEFINES')) {
        define('JPATH_BASE', $joomlaRootFolder);
        require_once JPATH_BASE . '/includes/defines.php';
    }   

    require_once JPATH_BASE . '/includes/framework.php';

    // Instantiate the application.
    $app = \JFactory::getApplication('site');
    $app->initialise();

    // Breaks here!
    \MyGlobalLibrary::didNotFindClass();

The library works as expected in our Joomla code, so that's not the problem.

Edit: My solution was to manually call

    \JPluginHelper::importPlugin('system');
    \JEventDispatcher::getInstance()->trigger('onAfterInitialise');

Seems like this was not done in the $app->initialise() method.

As stated in my edit of the question, the solution was to include

\JPluginHelper::importPlugin('system');
\JEventDispatcher::getInstance()->trigger('onAfterInitialise');

after

$app = \JFactory::getApplication('site');
$app->initialise();
