Xdebug 3 has no effect on YAF framework breakpoints

Question

In $test = time();, there is no effect at the direct breakpoint. You need to break at $application->run() and then step into the effect. Why?

I expect the breakpoints directly on the Controller to work; I have no problem using other frameworks like Laravel.

index.php

$application->bootstrap();
$application->run();

Test.php

class TestController extends Yaf_Controller_Abstract
{
    public function indexAction($name = "Stranger") {
        $test = time();
    }
}
