Storyline max size of 2047 pixels: Larger Infographic possible?

Recently I've been wanting to try making an infographic like these using Storyline.

I know how to increase the size of the Storyline screen using Design > Story size > Custom > Width/Height.

I have even fiddled with the HTML output so I can make a very large screen scrollable (instead of Storyline shrinking it to fit on the screen when published.)

What I'd like to know is if there is a way around the max project size of 2047 pixels tall? Is there a bit of code somewhere we can change manually? Is it a built in limitation that can't be changed? If so, why is that the case?

Thanks.
