What Operating System are you using (both controller, and any agents involved in the problem)?

Windows 11

Reproduction steps

Look at the multi-pipeline-graph view for any pipeline and notice that the individual pipeline run graphs are centered.

For a more obvious test, create a pipeline with varying number of stages between runs:

currentBuild.getNumber().times { i ->
    stage("Stage ${i}") {
        echo("Done")
    }
}

Expected Results

The pipeline run graphs on the multi-pipeline-graph view are all left aligned.

Actual Results

The pipeline run graphs on the multi-pipeline-graph view are all centered.
