See context in ENG-848 – on prod it's not working, and it's causing serious performance effects on the Node server backend as well as causing the website to take 15s to load.

Best I can do is test yarn prod in my local environment. From investigating the prod web environment with Chrome Dev Tools, I'm pretty sure this is a safe change
