Current behavior:
this.customEvent.emit() returns a boolean even though according to the declaration it should return CustomEvent<T>.

Expected behavior:
Either emit() should return a CustomEvent or the type declaration should be changed.

Steps to reproduce:
Emit any custom event in a Stencil component and check its return type.

Related code:

import { Component, Event, EventEmitter } from '@stencil/core';

@Component({
  tag: 'my-component'
})
export class MyComponent {

  @Event() someEvent: EventEmitter;

  componentDidLoad() {
    if (typeof this.someEvent.emit() === 'boolean') {
      alert('Boolean was returned');
    }
  }

Type declaration:

export interface EventEmitter<T = any> {
    emit: (data?: T) => CustomEvent<T>;
}

Other information:
The implementation of emit() returns the result of dispatchEvent which, according to MDN, is a boolean indicating whether the event was cancelled (i.e. at least one of the handlers called event.preventDefault()).
