Jetbrain Peacock theme doesn't highlight "Undefined class"

Whenever you're missing an import, peacock theme won't highlight undefined class

In PhpStorm you can work around this issue by adjusting the setting for PHP Undefined classes. Search for 'undefined' in the IDE settings and change the severity for PHP 'Undefined class' from warning to something else. I used typo, but others seem to work as well.
