It should make the view scroll down to tail the log.

To reproduce:

node {
    stage('yeah') {
        sh 'ping -c 40 www.apple.com'    
    }   
    
    stage('shorty') {
        sh 'ping -c 5 www.apple.com'
    }
    
}

Run this as a basic pipeline, and as long as your screen height isn't too high, you will see it.

This should follow along with the log. When the log completes, it would be folded away, and it starts again.
