Slide content is cut off when shown if full screen mode

https://intro-r-rstudio.nhsrcommunity.com/session-packages.html#/package-locations is a good one to check this as it cuts off the last few lines in full screen mode but shows the full screen if it's put side by side with another screen. I never noticed this as I'd use the Cloud/RStudio next to the slides to refer to them while live coding.
