Duplicated entries with inverse relation

If I duplicate an entry with the Duplicate action (Tailor) and the entry has an inverse relation…the related entry is also duplicated.

My Blueprints looks like this:

handle: Catalog\Campaigns
    label: Articles
    type: entries
    source: Catalog\Article
    inverse: campaign
    column: invisible
    scope: false
handle: Catalog\Article
      tab: Campaigns
      label: Campaign
      span: row
      spanClass: col-12
      type: entries
      displayMode: relation
      maxItems: 1
      source: Catalog\Campaigns

When duplicating a campaign, the article is also duplicated. I did not expect this. Is this a bug?
