When users add new lines using shift-enter, the text moves out of status box. Same for cursor.
When users add 2 line breaks using enter key, the thumbnails for backgrounds (at the bottom) vanish from the statusbox.
Also the height of the statusbox after posting doesn't return to default state. The statusbox is empty, but behaves as if there would be content. Users need to refresh browser window in order to get back to default height.
