Change Details

EventLogging's main session ID is supposed to persist until a user has been inactive for 30 minutes. However, I've noticed that `mw.eventLog.id.getSessionId()` returns a different ID on every pageview, no matter how short the interval between them. ~~If this is widespread, it will seriously break a lot of our metrics,~~ although the [session length dashboard](https://superset.wikimedia.org/superset/dashboard/232/) looks normal so either it's not widespread or it was just introduced in #mw1.39.0-wmf.23. I've tested this on Firefox 103.0 and Safari 15.5 (17613.2.7.1.8) and the result is the same.
