Re: [pointerevents] Expose 'inertial scrolling state' in wheel events (#587)

@StephenHaney Could you please file a new issue in this repro with more details about your use-case? In particular, please clarify:
- if you wanted a new trackpad swipe to "extend" the momentum phase of the previous swipe or not, and
- why new modifier key state is related to sign changes in delta.

FYI: The momentum bit is available in Chrome M150 (current Canary) when run with the command-line flag `--enable-blink-features=WheelEventMomentum`. I updated [this repro](https://codepen.io/mustaqahmed/full/MYjGMVG) to emit modifier states in the console, which shows that a change in modifier key interrupts an ongoing momentum phase. Not sure what's the expectation here. In any case, please report this in a new issue.
