--- Comment #1 from David Kilzer (:ddkilzer) <ddkilzer at webkit.org> ---
Note that when DragState::type is changed from OptionSet<> to Optional<>, then WTF::Optional<>::hasExactlyOneBitSet() and WTF::Optional<>::toSingleValue() may also be removed.

The need for both of these methods are also indicative of the need to change DragState::type to Optional<>.
