Issue with menu that is taller than the viewport with submenu items

When updating to the latest version, it seems there has been some functionality added to scroll the menu if it becomes too tall. This is great, but it doesn't seem to work in tandem with submenus. I'm not longer able to access the submenus once this special scrolling kicks in.

Here's an example:

    <head>
        <title>Submenu example</title>

    </head>
    <body>
        <span class="context-menu-one btn btn-neutral">right click me</span>

            $(function(){
                    /**************************************************

When I click on the submenu items at the top, they do not open as one would expect:

I feel like this is likely just a permutation that wasn't tested, but it would be nice to have. This becomes more apparent on a mobile phone.
