CKEditor not honoring config.format_tags

[dreerr]

Hi there,

when I try to override the default Format menu in CKEditor for a specific field or also for all fields according to docs creating a file at:

site/modules/InputfieldCKEditor/config-biography.js

with contents

CKEDITOR.editorConfig = function( config ) {
  config.format_tags = 'p;h2;h3;Heading';
};

the changes are not reflected. Other config item like config.uiColor are working. Any solution? For now I moved everything to the style menu...

EDIT: sorry, I oversaw the field
