Summary: A DataDevice will have zero or one active DataSource as the seclection. In the existing code we track the current data device then update it to the newest data device when the source inside a data device changes. If we store the active data source inside Seat instead of the device everything becomes somewhat simpler and safer. An entire unit test vanishes as that case of an externally set DataDevice with no source can no longer happen. There's also a lot of duplication that's been merged in this patch so we have one path. There are some technical behavioural changes in particular we do cleanup when the source vanishes rather than the data device, but if anything that seems safer and more correct. It's a precursor for introducing an abstraction class round the source without needing to meddle with too much code. Test Plan: Relevant unit tests passed, ran with it for a while with no issue.
