Am I right in assuming this:

if (class_exists($className))
{
	$plugin = new $className($this->getDispatcher(), (array) $plugin);
}

should be this:

if (class_exists($className))
{
$dispatcher = $this->getDispatcher();
$plugin = new $className($dispatcher, (array) $plugin);
}

??

@C-Lodder Your proposed fixed the issue. Please go ahead to make a PR for it. I think moving $dispatcher = $this->getDispatcher(); outside the foreach loop would be better
