I'm not sure if this can be called from a code path after the node has become
unreachable. For example, |AudioNodeInput::disconnect| calls changedOutputs and
sounds like a method that might be called during weak-processing/finalization (I
can't see any indication that it is, but it is hard to verify that nothing
transitively hits canUpdateState from weak-processing/finalization).
