Using the pipeline script in 53587 - If you run this in a non-blue-ocean, it'll show everything as passing while executing, despite the job running

All previous jobs were removed..   I've observed this also in a script I wrote to test multiple docker containers for basic functionality where they're green before being fired up.

Enclosed pictures are what my docker image testing job looks like visually when it's spun up (all green, despite there not even being containers launched yet), and then also the script from 53587 - launched and completed.

When it fails, it does go red, but it's green until then.  

I don't know if this is intended behavior to have it green, but it's confusing to our developers and even to myself to some extent where this should more show a pending state of some-sort rather than all green.

I also used the workflow-aggregator as the component since this seems to do the import of all the components to make pipelines possible.

All of my plugins are current as of this posting, I can provide a longer list if necessary, but figured since this was similar to blue ocean issues, perhaps it's something more underlying.
