ViewModels with more than one MutableLiveData get their nullability wrong.

Example:

class ExampleViewModel : ViewModel() {

    val data1 = MutableLiveData<Int>()

    val data2 = MutableLiveData<Int?>()

    fun funct() {
        data1.value = 1
        data2.value = null
    }
}

This gives the error Error: Cannot set non-nullable LiveData value to null [NullSafeMutableLiveData]
