amp-sidebar is being removed

[sarath49]

While trying to use amp-sidebar more than once on same page, it removes all other amp-sidebar except for first.

I am facing issue as in #3320 of amphtml issues log, while plain html works fine, while implementing it in drupal 7 websites second implementation of amp-sidebar is seems to be removed by Lullabot amp-library.

This is the sample html where second implementation of amp sidebar is being removed.

<amp-sidebar id="section" layout="nodisplay" side="left">
    <span>
      <a class="close" on="tap:section.close"></a>
    </span>
    <ul>
      <li><a href="#" class="plus" on="tap:item.toggle">Section</a></li>
      <li><a href="#" class="plus" on="tap:item.toggle">Section</a></li>
    </ul>
  </amp-sidebar>
  <amp-sidebar id="item" layout="nodisplay" side="left">
    <span>
      <a class="close" on="tap:item.close, section.close"></a>
      <a class="back" on="tap:item.close"></a>
    </span>
    <ul>
      <li><a href="#">Item</a></li>
      <li><a href="#">Item</a></li>
    </ul>
  </amp-sidebar>

Thanks

A test case with valid AMP HTML with more than once amp-sidebar ends up being removed by lullbot amp library

This is no more a bug in AMP Project and has been added and is being used in current implemtation of AMP Project with amp-sidebar being used more than once.

https://github.com/ampproject/amphtml/issues/6104

However, Lullabot amp library removed any other implementation of amp-sidebar.
