Suggestion (Interactive Book) : Make menu follow scroll
When the book content is too long, the menu become out of reach and the user have to scroll top to click on the menu.
It would be nice if there was a way to make the menu "follow scroll".
As the h5p iframe can be embeded on a website with a different origin, this doesn't seems possible to make it follow scroll exactly.
A solution could be to maybe use mouse position ?

Not perfect but better than nothing.
It could also be possible to use the wheel event (while still using mouse to position menu).
