On Blue Ocean 1.3.5, on the Blue Ocean Editor,, when you load a Jenkinsfile (declarative sytax) containing the new "libraries" syntax, the argument passed to the "lib()" function is cleared.

Reproduction:

• Clone this repository: https://github.com/oufti-playground/lab-vm
• Go to "docker" folder and start the stack with "docker-compose up -d"
• Once started, open http://localhost:10000 (user / password are always butler / butler )
• On the "demoapp" project on the local Gitea server (http://localhost:10000/gitserver/butler/demoapp), create a new Jenkinsfile with the following content:

  pipeline {
    agent any
    libraries {
      lib('deploy')
    }
    stages {
      stage('Hello') {
        steps {
          echo 'Hello'
        }
      }
    }
  }
  

• Note that a shared library is already configured on jenkins, and named "deploy" (cf. https://github.com/oufti-playground/lab-vm/blob/master/docker/jenkins/ref/init.groovy.d/addSharedLibrary.groovy)
• Load the project on Blue Ocean Editor (need to add the project as "Git" repo, with the SSH URL + add the SSH public key generated by Jenkins)

Expected Result:

I can load the pipeline, and save it without change. It should be idempotent.

Current result:

the pipeline is changed to (while we did not changed anything outside loading/saving on the editor):

pipeline {
  agent any
  libraries {
    lib('')
  }
  stages {
    stage('Hello') {
      steps {
        echo 'Hello'
      }
    }
  }
}
