Offending piece of code:
in TributeMenuEvents.js
this.tribute.range.getDocument().addEventListener('MSPointerDown', this.menuKeydownEvent, false);

My piece of code (react + flow):
class AddCommentComponent extends Component<{}, {}> {
constructor(props) {
super(props);

}

render() {
return

<Tribute
options={{
values: [{ key: 'Test McTesterson', value: 'test' }]
}}
>
<textarea></textarea>

</div>;

}
}
