Course Presentation unqiue zoom out when clicking slides

Hello!

I don't know if this is a bug or something I caused but I have something like a zoom problem with h5p course presentation.

1. I created a course presentation in h5p and uploaded an interactive video (no youtube video). Then I inserted a Drag & Drop Question and clicked "done". Now if you run the video until the question pops up you can click on the blue slide under the video to zoom it out. The problem is not caused when using youtube links instead of an own video.
2. Platform: Moodle 3.6 but even self created elements on h5p.org
3. Desktop
4. Browser: Firefox
5. H5P 1.17.2
6. Course Presentation https://h5p.org/node/619174
7. /
8. /
9. Look below (Second screen is after clicking the blue slide)
10. No changes to environment
11. No changes in browser

Hope this helps to understand my problem.
