mouseover event shouldn't fire if the pointing device wasn't moved

When I scroll a page using the keyboard, if an element with a mouseover event attached ends up underneath the mouse pointer (e.g. an element with a menu behaviour) then the event is fired (the menu is displayed).

I don't expect the menu to be displayed in this scenario, because I didn't actively move the mouse pointer to the menu element.

Note that in the documentation for mouseover, mousenter, etc. it says that the

  "event is fired when a pointing device is moved onto the element that has the listener attached"

(See: https://developer.mozilla.org/en-US/docs/Web/Events/mouseover)

As stated above, I didn't move the pointing device (mouse) onto the element, so I don't think the event should fire.

Amending this behaviour as per the documentation/specification would improve the UX a lot in pages that (incorrectly) use mouseover to display menus, IMHO. (They should be using mouseclick in most cases.) For example, if I navigate to a new page and my mouse pointer just happens to be over a menu element when the page finishes loading then the menu shows - often masking the content I wanted to see.
