    MouseWheelEvent Redirect 1

    This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

    Note: Gecko doesn't have a plan to implement this feature due to legacy event and non-standard.

    The DOM MouseWheelEvent represents events that occur due to the user turning a mouse wheel.

    Use standardardized WheelEvent instead of this legacy event object if available.
