The codepen demonstration here (https://codepen.io/VHall/pen/BrdwLz) is supposed to download an SVG file which wil l show the exact same image as seen in the browser when opened in Illustrator. Using Ai version 2020, the opened SVG shows the correct background image with the logo. However, opening in Ai 2021 does not show the image. The element not rendered starts with: "<image overflow="visible" width="1200" height="750" xlink:href="data:image/png;base64"
