Scrolling within storyline block

Hello,

I'm creating a course in Rise that includes a number of simulations that were created in Storyline. I've added these in as Storyline Blocks, and it's mostly working great. The problem I'm having, however, is that when you scroll down the page of the course, if your mouse is in the storyline block, it scrolls down to a blank space. This seems to only occur when using Internet Explorer to view the course through our LMS. Can this be avoided? 

Thanks!
