Color Background in Section Not Extending Full Length Until Reload

Hi,

Site: candyculver.comPage: https://www.candyculver.com/clients-case-studies-1Bottom of page section: "The rest of the story"

I have a dark blue background on this section on which I have added an expanding Q&A using a markdown block with the code below. The blue background has a gap of white at the bottom the first time you visit the page. After that, it's fine. Can anyone help me with how to make the white gap not happen on initial visit?

The markdown block code:

@jenniferdonahue Post your code by clicking "101 010" icon

Oh my gosh thank you! :)

<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>

<script>      $(document).ready(function(){

   $('.markdown-block .sqs-block-content h3').css('cursor','pointer');

   $(".markdown-block .sqs-block-content h3").nextUntil("h3").slideToggle();

   $(".markdown-block .sqs-block-content h3").click(function() {$(this).nextUntil("h3").slideToggle();});

   });    </script>

disable ajax loading
