HTML5 issue on Safari
We have a HTML5 course and a user on Safari 12.1. They are having an issue with the drag and drop interaction.
One of the drag and drop elements has not shown up at all (so they can't drag it!) and they are able to drag the item that is actually meant to be a fixed, drop state. All very confusing.
They've disabled their adblocker, and tried refreshing the page but it doesn't make any difference.
Anyone any ideas what's going wrong?
