Specification https://w3c.github.io/pointerevents/#dom-wheelevent-momentum Summary The wheel events on many native platforms simulate scrolling inertia: the events continue to fire for a while after the user has lifted the finger from the trackpad after a fling interaction. This feature exposes a momentum attribute in wheel events which is true only for those simulated events, differentiating them from the events fired during the physical scroll interaction. This lets web developers ignore fling events or customize rich fling effects.

Please list open issues (eg links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (eg, changing to naming or structure of the API in a non-backward-compatible way).
