Interactive Video

I would love for content in Interactive Books, such as Interactive Videos, to resize when going into fullscreen. Alternatively, there could also be a fullscreen mode for child content types. As this user has already pointed out it seems impractical and unintuitive that there is no fullscreen mode for Interactive video within other Content Types.

Using Javascript event listeners, I tested the demo content for Interactive video – the 'Smoothie' activity here: https://h5p.org/interactive-video#example=617

Some content types, even though available and working in the content bank, gives the following error when trying to access from the content bank: 

invalid-library-json-file : Could not find library.json file with valid json format for library filesaver-1.0
