Broken stylesSet since v4.7.2

[trsteel88]

Since v4.7.2 styleSets I use a broken.

CKEDITOR.editorConfig = function( config ) {
    config.stylesSet = [
        { name: 'Intro', element: 'p', attributes: {'class': 'intro'} },
        { name: 'Primary button', element: 'a', attributes: {'class': 'btn btn-primary'} }
    ];
};

In the above example, the primary button doesn't show in the styles dropdown.

Is anyone else having a similar issue?

Fyi, the intro style appears. However, any styles for a links fail.
