incorrect event received with workflow-api 2.8

XMLWordPrintable

      After upgrading workflow-api from 2.7 to 2.8, blueocean tests started failing. After debugging with svanoort it was discovered an extra event from next branch was was received (so two input step events for left branch in stead of one) from this sample pipeline script below. It results in to incorrect visualization of steps when user selects parallel branch nodes.

      node {
    stage "hey"
    sh "echo yeah"
    
    stage "par"
    
    parallel left : {
            sh "echo OMG BS"
            echo "running"
            def branchInput = input message: 'Please input branch to test against', parameters: [[$class: 'StringParameterDefinition', defaultValue: 'master', description: '', name: 'branch']]
            echo "BRANCH NAME: ${branchInput}"
            sh "echo yeah"
        }, 
        
        right : {
            sh "echo wozzle"
            def branchInput = input message: 'MF Please input branch to test against', parameters: [[$class: 'StringParameterDefinition', defaultValue: 'master', description: '', name: 'branch']]
            echo "BRANCH NAME: ${branchInput}"
        }
    
    stage "ho"
        sh "echo done"
}

      Here are the events generated and this is extra event generated failing test: https://gist.github.com/vivek/ccf3a4ef25fbff267c76c962d265041d#file-event-log-log-L3.
