Fixes #23281. Part of #20613. We were emitting the `online` event in the constructor, so the caller could never receive it (since there was no time for them to add a listener). Instead, emit the event where it's intended – after the worker is initialized. --- After this parcel no longer freezes, but still will fail due to other bugs (which will be fixed in other PRs)
