interactive book

When a user tries to view an H5P for our course, they aren't able to advance beyond page 2, when they arrive there they cant go back to the first page either. 
I checked the logs and found the following error message:

The table editor has been updated in the past year i believe, and i am struggling to get the tables i create to display as full width. By default, they just display to the width of the length of content you put in there. I just want it to be full width but i dont know the dimensions to put into the editor. Its a bit confusing. Is there an easier way? When i drag the borders around, it looks messy, and i cant get it to be full width that way anyway. 

Here is a screenshot from my course.

Hi, it seems that the Audioplayer stops when it´s scrolled out of the viewport/Window. This only happens in fullscreen mode, not in the embeddeed frame. 

I tested this in the interactive book 1.13.5  and Page 1.20.2 libraries. I didnt test it with the videoplayer. I am using the wordpress plugin. 

I was working in the previous version without the new design. Is there a way to change that behavior. I want to keep the player running regardless if it was scrolled out of the viewport. 

Many thanks in advance!
