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
We should add documentation that explains how to properly handle code that was previously in an overwritten setUserVisibleHint(). (Code executed when passing in 'true' should be moved to onResume(), while code executed when passing in 'false' should be moved to onPause())
