So this is the iFrame HTML the embed code is outputting:
<div style="position: relative; padding-top: 56.25%;">
<iframe src="https://iframe.mediadelivery.net/embed/64919/2f849023-0e86-4152-b6eb-5f9ec2993340?autoplay=false&muted=true" loading="lazy" style="border: none; position: absolute; top: 0; height: 100%; width: 100%;" allow="accelerometer; gyroscope; autoplay; encrypted-media; picture-in-picture;" allowfullscreen="true"></iframe>
</div>
In the iframe you will see this inline style:
style="border: none; position: absolute; top: 0; height: 100%; width: 100%;"
Can that be changed to:
style="border: none; position: absolute; top: 0; left: 0; height: 100%; width: 100%;"
