Don't know if this is quite the same but I worked for a company on a React SPA that was essentially an event driven CAD system using the Canvas API. It was an absolute nightmare - there were a ton of unintended event loops and side effects. When I left one of the seniors was in the process of converting it to using a game loop under the hood which sounded like it was going to solve a lot of the issues but it took him a lot of time and effort to convince management to let him do it. Tbh, I think it was more a case of the app getting so slow and buggy that it was causing them embarrassment in front of clients which made them cave to his requests than his methods of persuasion.
