Inline widget gone on drop with basic editor setup

[Olek Nowodziński]

Use the following setup of the editor:

CKEDITOR.replace( 'editor1', {
	plugins: 'toolbar,dialog,basicstyles,wysiwygarea',
	extraPlugins: 'placeholder'
});

Drag the inline widget and drop it. It's gone (see attached screencast)

It also happens to inline image2 widget.
