Drupal Quiz with H5P questions not working in IE
H5P questions for Drupal quizzes are not showing up at all in Internet Explorer 10 or 11 (and possibly other versions of IE, but I have not tested them). The page for each question is presented, but the content is empty. I'm using version 7.x-1.22 of the H5P module, 7.x-4.0-rc5 of the Quiz module, and all of the latest H5P libraries.
I reported this issue in the Quiz issue queue (https://www.drupal.org/node/2836269), but I'm not entirely sure it is being caused the Quiz module because the problem was first reported after an update to the H5P libraries, even before I updated the Quiz module to 7.x-4.0-rc5 (released Dec. 5).
You can see an example of this problem with this sample quiz (consisting of just two multiple-choice questions): https://foxylearning.com/quiz/ietest
