[list-pages] and [child-pages] return broken markup for first item

Massively useful plugin, thank you, but i am having an issue with the generated markup:

Using [list-pages] or [child-pages] returns expected list of items, but the first element in the list is marked up with a different nesting of HTML-tags than all the consecutive elements.

Specifically, the first element is nested first in an <li>, then in a <code>-tag, while alle the other elements are nested inside a single <code>-tag with each elements’ individual <li>-tag inside:

<ul class="list-pages-shortcode child-pages">
    <li ... >
        <code>
            <a href="...">Text of first element</a>
            <ul class="children">...</ul>
        </code>
    </li>
    <code>
        <li ... >
            <a href="...">Text of second element</a>
            <ul class="children">...</ul>
        </li>
        <li ... >...</li>
        <li ... >...</li>
        <li ... >...</li>
    </code>
</ul>

This breaks presentation and makes it impossible to format the listings correctly using, for example, flexbox. Could all elements, including the first one, be made to appear inside the <code>-tag, or individual <code>-tags be generated for each <li>-element?

Using plugin version 1.7.4
