context-menu appear on the left of the window when i'm closing it

- `react-use-context-menu` version: 0.1.4
- `node` version: 12.18.2
- `yarn` version: 1.22

What you did:
i have a project which render a document list and i use context-menu on its elements.

What happened:
when i close the context menu with a left click, the context-menu closes and reappear during 1 frame on the left side of the viewport.

unfortunately, i can't reproduce it on codesandbox

Problem description:
on /useContextMenu.js, the `setStyles(baseStyles)` doesn't keep the top and left position of the context-menu before disappearing

Suggested solution:
replace it with
```
setStyles({ ...style, position: 'fixed', opacity: 0, pointerEvents: 'none' });
```

Open /useContextMenu.js and inspect how the menu styles are reset when a left click closes it. Reproduce the close interaction with a document-list context menu and verify that the menu does not briefly reappear at the viewport's left edge while retaining its previous position.
