CMSApplicationWhen Joomla does its initial routing in Joomla\CMS\Application\CMSApplication in the route method, the JUri object is cloned. The line is:

$uri = clone \JUri::getInstance();

Looking at the code for \JUri::getInstance(), when called without a parameter, it will contain the URI based on the SERVER variables.

Why is this cloned, rather than just assigned?
