Custom config settings not working

I've tried adding custom config settings in various places but CKEditor doesn't seem to be using them.

I've tried to add the following:

  config.allowedContent = true;
  config.filebrowserWindowHeight = 1000;
  config.filebrowserWindowHeight = 700;
  config.filebrowserWindowFeatures = 'location=no,menubar=no,toolbar=no,dependent=yes,minimizable=no,modal=yes,alwaysRaised=yes,resizable=no,scrollbars=no';

And I added these to the various documented places without success:

• CKEditor > Profile > Advanced Options > Custom JavaScript configuration
• Set "Load ckeditor.config.js from the theme path" to yes, copied file to theme and added config overrides
• Added config overrides directly to /sites/all/modules/ckeditor/ckeditor.config.js
