Spotted in Home Assistant: home-assistant/core#64465

Will need to be rebased over #68 and #70

Thanks for merging.
I have a follow-up question about this one: in what context did you expect the ConnectionFailure to come up?

I was under the impression that it handled authentication failures, but in my own testing it didn't get raise on authentication failures at all (not when I pressed Deny, and not when I left it without pressing Allow or Deny)

Edit: let's not worry about the ConnectionFailure for the moment. We can always adjust later if there are more events being sent before the expected MS_CHANNEL_CONNECT_EVENT

Also: since this is a fix, it would nice to have a release again when you get a chance...

mmmh I think when TV refuses to connect

In HA, it is used incorrectly to trigger re-authentication in the config flow. I'll have to fix that there after the dependency bump...
