Vertical node tabs in References Dialog modal not accessible

Using the beta-6 release, in a modal powered by References Dialog only the first vertical node tab is accessible. Other tabs are visible but not accessible / clickable.

Maybe related to changes made for #114?

@olafgrabienski Could you test this PR and let me know if it's any better for you?

@laryn Thanks for the PR! At first sight, it doesn't make any difference regarding the issue. The vertical tabs (fieldsets in Gin) are still not accessible.

The PR looks quite big, by the way. Does it address other issues as well? Maybe a smaller fix could do the job here. Using the dev tools code inspector, I see that the following CSS prevents the fieldset content from showing up:

.js fieldset.collapsed .fieldset-wrapper {
  display: none;
}

Example fieldset:

<fieldset class="node-form-author collapsible collapsed form-wrapper" id="edit-author">
  <legend><span class="fieldset-legend">Authoring information</span></legend>
  <div class="fieldset-wrapper">
    <div class="form-item form-type-textfield form-item-name">
      <label for="edit-name">Authored by </label>
      <input type="text" id="edit-name" (...)>
      <input type="hidden" (...)>
    <div class="description">Leave blank for <em class="placeholder">Anonymous</em>.</div>
  </div>
  (...)
</fieldset>
