Given how long the ePub3 standard has been available, the shame is that so few apps and devices support more of it's features. Between Thorium on my desktop and my Kobo ereaders, I have no issues with fixed layout ePubs. From the chunk of the ePub3 you posted, the ebook is indeed a fixed layout which means just like a PDF, everything is placed in a absolute position on a fixed size viewport.
In your case, the ePub3 is also forced to landscape which makes it more fun to deal with.
May I ask you purchased a ePub3 version when you have no devices that will render it?
