Bugs in content types

Hello. I'm trying to embeed the code to my website, and it's displaying blank, not showing. Did someone have this problem before and knows how to solve it? I have embeeded other websites and plugins on the same code and they work perfectly, perhaps this one doesn't. Thanks in advanced.

This is the code:

<iframe src="https://h5p.org/h5p/embed/478787" width="1090" height="450" allowfullscreen="allowfullscreen"></iframe>

Hi,

1. When you enter fullscreen mode in iOS for the Interactive Video content type, the address bar on top as well as the safari controls on the bottom are still displaying (see screenshots attached) and taking away a major part of the screen space, which makes the fullscreen mode pratically useless in landscape mode. Additionally, in Safari you are able to scroll up and down in fullscreen mode as the video is not fixed to width:100% and height:100%.

Is there a way to adjust the image display size in the Documentation Tool? I cannot seem to find a way to adjust the size and it is rather large, would like ti to be smaller. Has anyone else had this problem?
