Build blocker plugin issue with node level blocking

[Denis Mone]

Hi all.

I have 2 jobs let's say job1, job2 on my Jenkins instance which i want to exclude from running at the same time, on the same node.

I have configured job1 to block on node level when a build of job2 is happening.

I have scheduled job2 to run every 2 mins on a specific node and job1 every minute on that same node.

What i see is the job1 is triggered normally while job2 is already building on the same node.

What's more interesting is that this does not happen when i set the blocking level to global.

This seems to me like a bug on the plugin.

job1

```

node("${agent}") {
    stage('stage 1') {
        echo 'Hi there'
        sh 'sleep 2'
    }
    
    stage('stage 2') {
        echo 'stage 2'
    }
}

```

job2

```

node("${agent}") {
    stage('stage 1') {
        echo 'Hi there'
        sh 'sleep 3m'
    }
   
    stage('stage 2') {
        echo 'stage 2'
    }
}

```
