JavaScript error when importing as resources

[squarepegsys]

It seems that the bundling of the the Foundation Javascript is causing it not to load correctly.

I have the following in my layout:

<r:require modules="foundation-css,jquery,foundation-js,foundation-topbar-js"/>

<g:layoutHead />
<r:layoutResources />

When I load the page, I get this in the JS Console:

    Uncaught ReferenceError: Foundation is not defined

and the mobile menu does not work.

If I remove the Foundation JS and use a CDN like below:

<g:layoutHead />
<r:layoutResources />

<script src="https://cdnjs.cloudflare.com/ajax/libs/foundation/5.5.0/js/foundation/foundation.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/foundation/5.5.0/js/foundation/foundation.topbar.min.js"></script>

I don't get that error and the mobile menu is fine.
