Display issue with embed on Drupal 8
I am currently experiencing an issue using the embed code. I'm using a Drupal 8 website and installed HTTP Response Headers to enable iframing. When I use the embed code inside of another tool called Cogbooks, the webpage looks cut off (screenshot1.png.) When I take the same embed code from my Drupal 8 site and place it in an HTML file and open it in a browser, the H5P interaction also appears fine (screenshot2.png.) However, when I create a H5P interaction on the h5p.org website and embed it in Cogbooks, the H5P interaction appears fine (screenshot2.png.) I cannot seem to rule out what might be causing this dislay error. Has anyone encountered a similar issue or have any suggestions for me to try?
