Tutorial screenshots don't animate on Safari

Steps to reproduce

I downloaded the native Mac app but sign up flow led me to Safari, my default browser. Which led to the tutorial.

It reproduces as well if you choose Start Tutorial from menu

Trying clearing your caches. Go to Safari Preferences => Advanced and at the bottom, check “Show Develop menu in menu bar.” Then go to Extension and disable any that you have installed. Then go up to Develop => Empty Caches. Go back to that website and see if the GIFs load.
