Non-cancelable event

[Rowan Cockett]

I am getting errors in the noevent.js file saying:

Ignored attempt to cancel a touchmove event with cancelable=false, for example because scrolling is in progress and cannot be interrupted.

The advice I have seen around the internet is to add a:

export default function() {
  if (event.cancelable) event.preventDefault();
  event.stopImmediatePropagation();
}

Let me know if you want me to open a PR!

This seems similar to d3/d3-zoom#195 and d3/d3-zoom#175 ; it would be nice to be able to reproduce the issue with a given webpage and browser.

This happens to me as well in an Ionic (https://ionicframework.com/) project with the touch inputs turned on in Chrome.

I suspect it may be related to the ion-content since it has it's own scroll logic.

I believe this was because the event listeners were not declared non-passive, which was the historical default, but broken in recent browsers. Hence, this is a duplicate of #78 which is now fixed.
