While trying to run reftests on a QuantumRender build I was hitting crashes because the WebRenderBridgeParent was trying to call ScheduleComposition on a null mCompositorScheduler. It seemed like the "parent" WRBP had already cleared the mCompositorScheduler, but the "child" WRBP had a ref to the parent and was trying to schedule a composite.
