Fix the representation of Parallel Stage in pipeline build (as it is delivery pipeline view)

1) With a Pipeline build
This is my pipeline script

node {
stage 'compile'
git 'https://github.com/hermod/hermod-java-ser-impl.git'

def mvnHome = tool 'maven-3.3.9'
sh "${mvnHome}/bin/mvn -DskipTests clean install"

def deployments = [:]
deployments["dev"] =

{ stage 'deployOnDev' echo 'deployOnDev' }

deployments["uat"] =

{ stage 'deployOnUat' echo 'deployOnUat' }

parallel deployments

stage 'deployed'
echo 'deployed'

}

See the representation in pipeline-screenshot.png

2) With n build + Delivery Pipeline View
See the representation I want to have in delivery-pipeline-view-screenshot.png

I'm not sure but it seems close to this issue https://issues.jenkins-ci.org/browse/JENKINS-33185

Thanks in advance
