Solved an issue with Microsoft Edge compatibility

[usolved]

Sorry that I didn't make a pull request for this. But hopefully it'll help somebody who searches for this problem, likes to have Edge compatibility or want to make a PR. The function "getBoundingClientRect" doesn't have "x" and "y" available in Edge. But these values are also stored in "left" and "top". So rewriting the following will then also work with Edge:

calculateLastEvent: function calculateLastEvent(t) {
  ...
  //instead of
  r = o.x + this.width / 2,
  s = o.y + this.width / 2,

  //rewrite to
  r = o.left + this.width / 2,
  s = o.top + this.width / 2,    
  ...
}

It's also possible to have IE11 compatbility when replacing all "includes" with "indexOf". For example:

//instead of
var e = t.disabled.includes(t.defaultValue);

//rewrite to
var e = t.disabled.indexOf(t.defaultValue) > -1;

The only problem left for IE11 is to polyfill "find" with the following:

Thanks for this really nice and well designed component. Looking forward to use it :).
