Stages Graph Behavior in Parallel Execution

not sure how to define it, as a bug or feature. sorry.. Am I missing anything?

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

RHEL9.2

Reproduction steps

The Stages Graph only appears when the stage declaration includes the parallel:

stage("foo") {
  parallel() 
}

Stages graph would not appear correctly when the stages declarations are inside parallel:

parallel(
   "bar": {
       stage("foo") {}
})

Expected Results

Seeing the stage names in the pipeline overview.

Actual Results

Seeing "parallel" stage, and inside you can see the actual stage names.
