The reason for the error is that your are removing event listeners concurrently, resulting in a race condition. Using the kroll thread, this was a non-issue, because the kroll-thread would just block the whole app, but using the (more performant) main thread, it does not anymore, resulting in this behavior. We will leave the ticket open for now for further investigations.",
