Blue focus outline on modals and slow click to dismiss

[chrismanderson]

When using version 6.2.4.0 of this gem, I see the blue focus outline around modals. However, I do not see this outline when doing a fresh install of foundation via the NPM installer, leading me to believe there is something amiss with the rails version. Not only that, there's clearly a delay present in dismissing modals with the outline than without; the browser takes a moment to clear the outline, then clears the modal.

How can we reproduce this bug?

1. Step one
   Install 6.2.4.0 of this gem into a Rails app.

2. Step two
   Open a modal.

    <div class="tiny reveal" id="exampleModal" data-reveal>
        <!-- ... -->  
    </div>
   
    <a data-open="exampleModal" aria-controls="exampleModal" aria-haspopup="true" tabindex="0">Click me for a tiny modal</a>```
   
   

3. Dismiss the model

What did you expect to happen?
There should not be a blue outline around the modal. The modal should not delay when closing.

What happened instead?
There was a blue outline around the modal and it delayed when closing.
