contextMenu.show doesn't work with onMouseUp Event

If we use contextMenu.show in combination with onMouseUp event the menu doesn't show up.

Example
```
import React from "react";
import { contextMenu, Item, Menu, Separator } from "react-contexify";

const MyComp: React.FC = () => {
const MyAwesomeMenu = () => (

Lorem

Ipsum

);

const showMenu = (e) => {
contextMenu.show({
id: 'id-1',
event: e
});
};

return (
<>

At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet.

);
}
```
The event onMouseUp gets fired but the contextMenu doesn't show up. If I use `onClick` instead of `onMouseUp` the context menus is shown. Does anyone knows how to get react-contextify work with an `onMouseUp` event?
