in my case: The producer has 3 spatialLayers(0, 1, 2), temporalLayers always 0.
1、now spatialayer is 2, due to some reason (may biterate not enough or business needs)，The producer don’t send the sream with spatialayer of 2
2、After SimulcastConsumer::increaseLayer, targetSpatialLayer was 1
3、In SimulcastConsumer::ApplyLayers, BWE Downgrade is tirggered.
question1: Why the BWE Downgrade waiting time is 10s ?
question2:Whether to trigger the BWE Downgrade due to the down switch of resolution caused by the producer？
