Never Use PHP filter in Drupal 8

For security reason, Drupal 8 resists using for PHP filter. PHP filter breaks the Drupal 8 site.

Since 8.3.x version this is NOT the case (NOT Valid). Now the site will not break after installation of this module.

Sample blackbox block

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Maecenas non porta odio, id mattis erat.

Nam sed tincidunt eros. Donec a venenatis odio, vitae commodo sem. Vivamus ullamcorper pellentesque erat, in adipiscing tortor scelerisque sit amet. Nulla pulvinar urna magna. Vivamus a ipsum lorem. Etiam adipiscing pulvinar lorem.
