Steps to reproduce

1. Fork the starter with the environment variaable #EXAMPLE=1 in the url.

phpmyadmin just needs this added to its config.inc.php file

$cfg['AllowThirdPartyFraming'] = true;

The fix will be to inject this snippet into public/phpmyadmin/config.inc.php during the workspace initialization
