When hitting the Enter key for a while, bubbletea sends lots of events and we may imply sending reselectAuthMode{} events faster than we can actually handle the cancellation/reauthModeSelection in the whole stack.
This never happened (ever) when using the example broker, but it may actually happen in a real world scenario where the broker may not cancel the requests quickly enough.
Do this instead of avoiding the handling of the reselectAuthMode event because it's better to prevent bubbletea to break our (fragile) system.
