The constructor method is not being called when a class is in the same namespace as the trait containing the constructor.

Works: class in global namespace:
Works: class not in parent namespace:

Doesn't Work: class in same parent namespace:

Test script:

namespace Test {
    trait Base {
        public $config = [];
        function __construct($config = [])
            $this->config = $config;

    class Config {
        use Base;

namespace {

    $test = new Test\Config(['foo' => 'bar']);

    echo isset($test->config['foo']) ? 'Success: foo is set' : 'Error: foo is not set';

Expected result:
Success: foo is set

Actual result:
Error: foo is not set
