I am using fullpage.js and the scroll does not work after the 'intro' class section. I am able to move upwards in the webpage but while moving downwards it stops after the 'intro' class section. I even tried using normalScrollElements but it still does not work. The code is as below:

<div id="fullpage">
    <div class="section">
        Hello
    </div>
    <div class="section">
        Hello
    </div>
    <div class="section">
        Hello
        <div class="intro">
            /* Dummy Text */
        </div>
    </div>
    <div class="section">
        Hello
    </div>
</div>
