Shoud "console.groupEnd" trigger "log.entryAdded" event even though it doesn't use the printer?

According to the console spec, console.groupEnd doesn't use the printer (see https://console.spec.whatwg.org/#groupend), but it looks like Chrome sends the event and Puppeteer expects it.
I guess it might be generally helpful to identify the end of the group. So maybe we should add an exception to send an event in this case even though this method doesn't use the printer.
