Menu open on hover

[Octavianus]

Feature Request

Hover on Menu component to open the submenu.

Problem description

There are a lot of use cases( Read receipt and More options) that will require open on hover for menu item, there is temp way to make it work https://codesandbox.io/s/gq6i0?module=/example.js
However, there are 2 major issue:

1. It won't work on submenu if a submenu of a submenu requires open on hover.
2. Open close state can't be gracefully handled when mouse out of the menu items area.

Proposed solution

There is existing very good solution for Popup to handle open on hover, probably adapt the same solution on menu item.
