Custom style with anchor element fails

[Olek Nowodziński]

The following anchor style is invisible on the list of available styles:

CKEDITOR.stylesSet.add( 'default', [
	{
		name: 'Custom anchor',
		element: 'a',
		styles: {
			'line-height': '18px',
			color: 'red'
		}
	}
]);

The following code also fails:

var range = CKEDITOR.instances.editor1.getSelection().getRanges()[ 0 ];
new CKEDITOR.style( { element: 'a', ... } ).applyToRange( range );

It is visible when accessing via getStylesSet though:

CKEDITOR.instances.editor1.getStylesSet( function( stylesDefinitions ) { 
	console.log( stylesDefinitions );
});
>>> [ Object ]

This problem is only for element: 'a'. It works with p and similar. Also in v3.
