After restart, having input step inside lock and several jobs waiting to acquire the lock, not able to Proceed or Abort anymore.

Steps to reproduce:
1) Have "input" inside a lock block
2) Start several build of the same job (the earliest will block on "input" and others block on "lock")
3) Restart Jenkins

Observed behaviour:
Can not Proceed or Abort the build with buttons anymore. Even generic abort button does not work for the build, have to "kill" it.

Expected behaviour:
One can Proceed or Abort the build.

Minimal pipeline to reproduce:

pipeline {
    agent none
    stages {
        stage('a') {
            steps {
                lock('lock-me-in') {
                    script {
                        input 'Are you okay?'
                    }
                }
            }
        }
    }
}

Output in the jenkins log:
