The patch is added tests for escaping Attributes. Since this was create the two test \Drupal\Tests\Core\Template\AttributeTest::testAttributeValues and \Drupal\Tests\Core\Template\TwigExtensionTest::testSafeStringEscaping have been added which are doing the same testing.
Based on that and there has been no response for more information, I am closing this issue.
#2506133: Replace SafeMarkup::set() in \Drupal\Core\Template\Attribute →
#2571673: Convert Views t() usage where it is used as an attribute value →
