In iOS platform, text font are not strictly required to fit within the UIFont.lineHeight. Some Thai characters with diacritics are rendered outside the UILabel/UITextView's bounds.
One solution is to increase the top margin of the UILabel/UITextView so we leave extra padding between the parent view's top edge and the top edge of the UILabel/UITextView (Like the _titleLabel in MDCAlertControllerView).
