Triggered builds section not displaying intermittently since upgrading to blue ocean 1.17

I have encountered an issue that severely limits the usability of the BlueOcean plugin when used with downstream jobs.

When triggering a downstream job BlueOcean normally displays the following section with a link to the downstream job, as introduced in JENKINS-38339

However, after upgrading to BlueOcean 1.17 this behaviour seems to have regressed:

There are a lot of comments on the original ticket JENKINS-38339 listing the same issue.

I am aware that this was once an issue for declarative pipelines and fixed as part of https://github.com/jenkinsci/blueocean-plugin/pull/1918/files

But I am running legacy groovy pipeline.

It is important to note that this does not always happen: sometimes a run will show the link, then when the exact same run is re-ran again it fails to show.

I have found this issue with both sequential and parallel pipelines where jobs are kicked off.
