I just updated to v6.0.1 and our web-worker is completing and being destroyed. With v6.0.0 and earlier, we were able to keep the thread alive, which is our desired workflow.
I noticed that some bug fixes went into the latest release to close the web-worker observable, but i'm wondering if something was either missed so that the terminateOnComplete option is no longer being checked, or if we were "lucky" that things were working as we liked before?
