    REGRESSION (276312 at main): EventHandler::handleWheelEventInternal no longer defers scroll wheel event handling completion
    https://bugs.webkit.org/show_bug.cgi?id=283860

    Reviewed by Alan Baradlay.

    276312 at main appears to have unintentionally changed the scope of the RAII deferrer in this method,
    such that it adds and then immediately removes a deferral reason (instead of lasting through the
    scope of the method itself). Restore the previous behavior, by pulling this out into a `unique_ptr`
    that's set only if `scrollableArea` is nonnull.
