Comment (by nigelnelles):

 We reproduced the error by adding a shortcode block to the site with the
 following code:

 [video src="https://example.com/video.mp4"
 poster="https://example.com/poster.jpg" width="800" height="450"
 autoplay="true"]

 With this shortcode on the site, the elements tab in the devtools shows:

 <!--[if lt IE
 9]><script>document.createElement('video');</script><![endif]-->

 When doing the same thing on the playground generated from the PR, this
 comment is not present which is the goal of the PR
