16658	Placeholder widget losses styling after switching to source mode.	kkrzton		"Custom styles can be added to style placeholders, e.g:

`{ name: 'Placeholder class', type: 'widget', widget: 'placeholder', attributes: { 'class': 'placeholder-class' } },`

More on styles - http://docs.ckeditor.com/#!/guide/dev_styles.

While styles can be applied on a placeholder widget properly, switching to source mode removes classes/styling so it cannot be restored while switching back to WYSIWYG mode.

== Expected result ==
The classes/styles are preserved while switching between Source/WYSIWYG mode.

== Actual result ==
The classes/styles are removed while switching to Source mode.

== Other details (browser, OS, CKEditor version, installed plugins) ==
The cause of the issue is the way placeholder widget is downcasted. It is downcasted to `[[placeholder_name]]` so there is no way to store additional attributes in the downcasted text/html.
