FLineBatcherSceneProxy doesn't implement the custom depth in its GetViewRelevance function.
Something like Result.bRenderCustomDepth = ShouldRenderCustomDepth(); is missing in that function.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-168059 in the post.
