Offline mdn content and auto revalidate: unneeded CPU usage

[bansan85]

I want to run the mdn content offline. When I run yarn start and open http://localhost:5042/en-us/docs/learn/getting_started_with_the_web, the page is always refreshed every 500ms :

Listening on port 5042

How can I disable this feature ? At the current time, I disabled JavaScript in Firefox but I don't like this solution. It looks to be related to swr and revalidation.

I tried to add REACT_APP_NO_WATCHER=true REACT_APP_DEV_MODE=false REACT_APP_WRITER_MODE=false when calling yari-server but it doesn't help.
