The `console.countReset()` API is being spec'ed at https://github.com/whatwg/console/pull/133 and tested at https://github.com/w3c/web-platform-tests/pull/10722. As of now, Node.js and Edge implement this API, and given that it is being added to the spec, we're expecting implementations to conform. Other implementation bugs can be found at the spec PR link.
