Page is scrolled when pressing space on a MenuItem link

### Provide a general summary of the issue here

Hi,

If you use an `href` with `MenuItem`, pressing SPACE on a menu item to select it will scroll the page. This only affects links.

Thanks 🙂

### 🤔 Expected Behavior?

Page doesn't scroll when pressing SPACE on a `MenuItem` that is a link, providing the same functionality as `MenuItem` buttons.

### 😯 Current Behavior

Page scrolls on pressing SPACE.

### 💁 Possible Solution

Either keep the scroll locked when pressing SPACE or only activate `MenuItem`s with the enter key.
