      When there is a single, running branch of a pipeline, the StandardChunkVisitor doesn't trigger `parallelEnd` or `parallelStart` for it's parent block.

      This works:

      node {
    parallel([
        "A": {
            stage("Build") {
                echo("Build A")
            }
            stage("Test") {
                parallel([
                    "A1" : {
                       echo("Test A1")
                    },
                    "A2" : {
                       echo("Test A2")
                    }
                ])
            }
        },
        "B": {
            stage("Build") {
                echo("Build B")
            }
            parallel([
                "B1" : {
                   echo("Test B1")
                   sleep(60)
                },
                "B2" : {
                   echo("Test B2")
                   sleep(60;
                }
            ])
        }
    ])
}

      We get `A<-A1` and `B<-B1,B2`.

      This doesn't:

      node {
    parallel([
        "A": {
            stage("Build") {
                echo("Build A")
            }
            stage("Test") {
                parallel([
                    "A1" : {
                       echo("Test A1")
                    },
                    "A2" : {
                       echo("Test A2")
                    }
                ])
            }
        },
        "B": {
            stage("Build") {
                echo("Build B")
            }
            parallel([
                "B1" : {
                   echo("Test B1")
                   sleep(60)
                },
            ])
        }
    ])
}

      (`B1` becomes a sibling of `A` - `B` is not listed in the graph until the build completes).

      It feels like this would have been reported already, but I can't find an issue - so raising just in case.

      Update:
      More specifically, in the second Pipeline - `parallelBranchEnd/parallelBranchStart` don't get called for `B` whilst the Pipeline is still executing. This is not the case once the pipeline is finished or in the first example.
