Losing required properties of rules

[WinterSilence]

As example: rule header_comment added as: 'header_comment' => ['comment_type'=>'PHPDoc'], and dont contain required property header.

Are they lost?
Using the example of the header property of the header_comment fixer, do you mean that you configure header with https://mlocati.github.io/php-cs-fixer-configurator and when you export the configuration you don't have the header property?

@mlocati exported the configuration don't have the header attribute

[WinterSilence]

@mlocati by default this attribute not existed in array, i'm think need add HTML attr required to inputs like this

[WinterSilence]

@mlocati if you add header_comment without optional confuguration:

<?php
return PhpCsFixer\Config::create()
    ->setRules([
        'header_comment' => true,
    ])

This is working for me:
