An UndefineFormatOperation undefines properties set in the leaf format to the text in the specified range (no change is made if the specified range is a single point). It undefines properties set in the paragraph format to any paragraphs at least partially within the range (or a single paragraph if the range is a single point). And it undefines properties set in the container format to any containers at least partially within the range (or a single container if the range is a single point).

This code snippet shows a use of the ApplyFormatOperation
class.
After an operation of this type is executed, the font size of the new TextLayoutFormat is
gathered, which can be used to update a display label or menu.
