If you create a job that runs other build that returns with currentBuild.result = 'ABORTED', the parent job will render its status as FAILED, while it should be ABORTED as well. It is visible same in blueocean and build-history.

To replicate create two piplelines, 

ParentPipeline with:

node any {
  stage ('BuildChild') {
    build 'ChildPipeline'
  }
}

and the other:

node any {
  stage ('ChildBuilding') {
    currentBuild.result = 'ABORTED'
  }
}

You will see that result of parent is rendered as failed
