Popup appearing on hover from a MenuItem clears the the selected menu

[marco-ms]

We have something like this:

<Menu
    items={items}
    pointing
    vertical
/>

One item is:

<Popup
    content={...}
    trigger={ <MenuItem /> }
    on={["hover"]}
    trapFocus={true}
/>

What happens is until the mouse cursor is on top of the MenuItem, then item is correctly selected, however when moving the cursor on top of the popup content, the selection is cleared, no item in the menu (still open) is selected.
I thought I can workaround this by specifying the activeIndex in the Menu when the mouse is on top of the popup, but maybe this can be fixed in the Menu itself?

I hope it makes sense.
