Having an issue with scrollbars not appearing in the new Bootstrap 4.1. Initially, when the page loads it's not large enough to need scrollbars. However, after some searches are conducted and the results are displayed, the page becomes larger than the window but no scrollbars are visible. Even trying overflow-y: scroll doesn't seem to work.
How can I make sure that scrollbars show up when the content exceeds the vertical size of the window?
<body>
// Navigation bar code
</nav>
// Main Jumbotron section
// Left Column for search results
// Right column for item details on selection from left column
<main role="main">
<!-- Main jumbotron for a primary marketing message or call to action -->
<div class="jumbotron JumboHeaderImg">
// Content inside the jumbotron
</div>
<div class="container">
<div class="row">
<!-- Left Column with navbar search results -->
<!-- Right column with details of item chosen from left column -->
</div>
<hr>
</div> <!-- /container -->
</main>
