PhpStorm IntelliSense for class_alias

Question

PhpStorm gives me full IntelliSense when I use the instructions above. For example:

use Framework\MVC\Route;

Route::setRoutes($routes);

But I use class_aliashow [does not even work in one file]:

class_alias("Framework\\MVC\\Route", "Route");

Now that I am writing Route::, I am not getting IntelliSense. In fact, it even shows some warning talking about an unknown class Route. How can I solve this problem?
