Jumping down to unknown location on the page

When first interaction is made with Interactive Video or iFrame Embedder, the page jumps / scrolls down to some location down the page (on iPhone/iPad).

We have many cases, especially when pages are long or there are more than one H5P on a page. It is impossible to find one's way back on long pages. :-( One case is here:

1. go to on iPad or iPhone https://eskript.ethz.ch/videosinteaching/chapter/interactive-videos/
2. Scroll down to the first interactive video, not further.
3. If you click in/on the play bar e.g. to see what the first interaction is (like in the middle of the play bar to see the middle part of the video),
4. the page jumps down.

When it has jumped once (or twice) it doesn't usually happen anymore. It always happens when the page has freshly been loaded.

We use WordPress (4.8) plugin 1.8.4 of H5P. Both interactive videos on the page above are version 1.16.0. We have the same problem with almost all iFrameEmbedder modules that contain stuff to do in them (e.g. Geogebra). Tested on iPad with Safari, Firefox and Chrome, on iPhone with Safari.

Thank you so much for looking into this and sharing some insight. We're a bit at a loss. And thank you for making the interactive videos working on iPhones (or was that the iOS update?)! Great work anyway. We love all H5P modules and the new Dashboard especially.
