Left clicking on trigger element doesn't hide context menu

First off: Thanks for this library! 🙂

I think I've found a bug.

- `react-use-context-menu` version: 0.1.4
- `node` version: 14.6.1
- `npm` (or `yarn`) version: 2.4.1

**Expected behaviour**
When the user left clicks on the div that triggered the context menu, the context menu should be hidden.

**Actual behavior**
If the user left clicks the div that triggered the context menu, the context menu is not hidden.
If the user left clicks somewhere else on the page, the context men is hidden.

Example: https://codesandbox.io/s/sad-shaw-yfrqk

In the example, right click the word "context", then left click the word "me". I would expect the context menu to disappear, but it doesn't. If you click anywhere else on the page, the context menu disappears.

Thanks! 🙂

Reproduce the issue using the linked CodeSandbox: open the context menu on “context,” then left-click “me.” Trace the React hook behavior for the trigger element and verify that a left click there hides the menu, while preserving the existing dismissal behavior for clicks elsewhere.
