If one defines a chart with Chart.yaml:

apiVersion: v2
name: willcrash
description: A Helm chart for Kubernetes
type: application
version: 0.1.0

dependencies:
- alias: elasticsearch-new
  name: elasticsearch
  repository: "https://helm.elastic.co"
  version: "*"
- alias: elasticsearch-legacy
  name: elasticsearch
  version: "*"
  repository: https://kubernetes-charts.storage.googleapis.com/

Only one of the two subcharts will get stored (even if the two are downloaded).

Is helm supposed to support this use case or is it an expected behavior?
