I'm using Next.js 13 (with the pages router) along with MUI for styling and the Supabase js client. Lighthouse testing shows an error that the browser prevent forward/back using bfcache because there's a BroadcastChannel with an active listener. I'm having trouble figuring out exactly where that's coming from or what to do about it.

I looked in all the js files that are available in the Network tab in developer tools, and none of them contain the text "broadcastchannel". I was able to find a reference to it in the Supabase Gotrue library, but I'm not sure if that's the cause or why it doesn't even show up in the js that reaches the browser. I also found it in a couple other places where it wasn't clear what it was related to (seemed like internal Next.js or dependency stuff).

Any ideas? Thanks in advance.
