Thanks for the detailed analysis. This may not be an issue anymore since we've started using Main.immediate there but I' not sure; I'll try to create a test case.

just emitting same live data reproduces the issue.
@Test
fun raceTest() {
val subLiveData = MutableLiveData(1)
val subject = liveData(testScope.coroutineContext) {
emitSource(subLiveData)
emitSource(subLiveData) //crashes
}
subject.addObserver().apply {
testScope.advanceUntilIdle()
}
}

Description
Version used: 2.1.0-alpha04
Currently if you're writing a custom navigator that has a NavHost that can be defined in XML, there's no way to use the same app:navGraph that NavHostFragment is able to use since that attribute is defined in navigation-fragment.
Besides making it hard to pick another name for same functionality (fracturing how to use different navigators), it also makes it hard for Android Studio to fill in the 'Hosts' panel in the Navigation Editor correctly for custom navigators.
