Interactive video in label and completion


I don't knows if it's a bug or a misusage but, in Totara (Moodle fork) we usually integrate h5p videos into labels.
We position the completion criterion on the video "on the learner must see the video to validate".
Since August we have noticed that the simple fact of the learner landing on the page validates the video without the learner having to click on play button. I am sure this was not the case before: to validate the video the learner had to click on play.
Is this a misuse or a problem due to an update or something else?
Thank you.
