Gitlab "needs/dependency" graph seems to be broken for dynamic pipelines

I’ve setup some dynamic pipelines using this technique described in the Gitlab documentation: Downstream pipelines | GitLab

Only is seems to completely break any pipeline dependency graphs… There should be dependency lines shown between stages, the “needs” tab is just broken, any pipeline visualizations in the pipeline editor just stop before the first down-stream pipeline.

Gitlab verison: GitLab Enterprise Edition 15.4.0-pre

I’d understand some limitations here with multiple downstream pipelines, but once the pipelines are dynamically generated, I’d expect Gitlab to at least produce the dependency lines on the individual downstream pipelines, and the “needs” tab not to crash.
