Mis sized buttons of CKEditor toolbar configuration interface

Problem

The buttons of the CKEditor toolbar configuration interface are mis sized.

Proposed resolution

Set the box-sizing of the buttons to content-box:

.ckeditor-buttons li .cke-icon-only {
    -webkit-box-sizing: content-box;
    -moz-box-sizing: content-box;
    box-sizing: content-box;
}

Remaining tasks

• Review the proposed patch.
• If the patch is accepted, apply this correction to the SASS sources and generate the CSS files from the LESS sources.
