Details

There is a case that WebRenderLayerManager::SetLayerObserverEpoch() is called before WebRenderLayerManager::Initialize() call.

Call stack was like the following.
 	mozilla::layers::PWebRenderBridgeChild::SendSetLayerObserverEpoch()
	mozilla::layers::WebRenderLayerManager::SetLayerObserverEpoch()
 	mozilla::dom::TabChild::RecvSetDocShellIsActive()
 	mozilla::dom::TabChild::ForcePaint()
 	anonymous namespace'::HangMonitorChild::InterruptCallback()
 	InterruptCallback()
 	InvokeInterruptCallback()
 	[External Code]

Let's actually make this a dupe of bug 1326421, since I think the part 2 patch on that bug (which hasn't landed yet) will be the thing that actually fixes this.
