Cross-browser `transitionend` event listener.

This module is based on [on-transition-end](https://github.com/jshanson7/on-transition-end), which no longer seems to be maintained and is not working properly. Also, it automatically infers the timeout based on the transition duration.

## Installation

`$ npm install proper-on-transition-end`


## Usage

```js
import onTransitionEnd from 'proper-on-transition-end';
// or
const onTransitionEnd = window.onTransitionEnd;

const cancelOnTransitionEnd = onTransitionEnd(element, [options,] callback)
```

- `element`: The element that is transitioning.
- `options`: You can pass a few options here:
    - `timeout`: This is automatically calculated for you, based on the longest transition of the element, using [`longest-transition`](https://github.com/IndigoUnited/js-longest-transition). Still, you can override that and pass the `timeout` in milliseconds.
    - `gracePeriod`: There is an implicit grace period of `100` milliseconds before the event times out, but you can tweak it using this option.
- `callback`: The callback that is called when the transition ends.


Calling `cancelOnTransitionEnd` will remove the listener and cleanup the timers.
