Breadcrumb item schema position appears in reverse order

[shazzad]

Issue

Breadcrumb item's position meta is coming in reverse order. It gets reversed after the home & docs item.

Outcome

<ol class="wedocs-breadcrumb" itemscope="" itemtype="http://schema.org/BreadcrumbList">
    <li><i class="wedocs-icon wedocs-icon-home"></i></li>
    <li itemprop="itemListElement" ...>
        <a itemprop="item" href="...">
        <span itemprop="name">Home</span></a>
        <meta itemprop="position" content="1">
    </li>
    <li class="delimiter">...</li>
    <li itemprop="itemListElement" ...>
        <a itemprop="item" href="...">
        <span itemprop="name">Docs</span></a>
        <meta itemprop="position" content="2">
    </li>
    <li class="delimiter">...</li>
    <li itemprop="itemListElement" ...>
        <a itemprop="item" href="...">
        <span itemprop="name">Level 1</span></a>
        <meta itemprop="position" content="5">
    </li>
    <li class="delimiter">...</li>
    <li itemprop="itemListElement" ...>
        <a itemprop="item" href="...">
        <span itemprop="name">Level 2</span></a>
        <meta itemprop="position" content="4">
    </li>
    <li class="delimiter">...</li>
    <li itemprop="itemListElement" ...>
        <a itemprop="item" href="...">
        <span itemprop="name">Level 3</span></a>
        <meta itemprop="position" content="3">
    </li>
    <li class="delimiter">...</li>
    <li><span class="current">Test Sub Article</span></li>
</ol>

Possible solution

if ( 'docs' == $post->post_type && $post->post_parent ) {
    $parent_id   = $post->post_parent;
    $pages = [];

    while ( $parent_id ) {
        $page          = get_post( $parent_id );
        $parent_id     = $page->post_parent;
        $pages[]       = $page;
    }

    $pages = array_reverse( $pages );

    foreach ( $pages as $page ) {
        ++$breadcrumb_position;

        $html .= wedocs_get_breadcrumb_item( get_the_title( $page->ID ), get_permalink( $page->ID ), $breadcrumb_position );
        $html .= ' ' . $args['delimiter'] . ' ';
    }
}

Thanks.
