In Moodle, if a create an H5P activity of type Quiz with more than four pages, the content keeps flicking or does not appear at all.
It seems that the bug show only on Desktop Chrome (on Mac), not showing on Firefox or Safari.
I'm attaching a link for an H5P quiz that triggers the problem:
Create the activity and try to refresh some times the page. Some times it will appear, some times it will not appear or keeps flickering.
