Storyline Block - How to go full screen?

Hi Articulate team,

I have a Storyline project sized 350 x 720, embedded in Rise with the Storyline width set to 'small'. When I view it on my smartphone, i can see the entire Storyline project. However, when I view it on my computer, it shows way too large, meaning that I have to scroll up and down in order to see the complete Storyline block.

Widening the Storyline project is not an option, since that makes the text too small to read when using a smartphone.

I've tried to embed the Storyline project in an iframe sized 350 x 720, but that doesn't work either. It looks like Rise does not do anything with the provided iframe sizes, except for defining the aspect ratio.

Is there any way to show the Storyline block in such a way that I can see its entire height without scrolling when viewing it on a computer?
