Description
Steps to reproduce
1. Run a pipeline and open the result modal
2. wait for the pipeline to finish
3. all nodes in the pipeline graph are ticked but the header never changes from the running state to a final success/failure screen. There are thousands of errors in the js console.
In Scope
- Fix the bug
- add a appropriate tests
MN Note: this seems to happen primarily on .io - which is remote, vs local. However tscherler believes he can reproduce it locally with the acceptance test harness. This is due to SSE events not arriving for some reason. Locally no one has been able to reproduce this in a browser.

I tried your steps to reproduce it but with out success on my local system, however the stacktrace
GET https://ci.blueocean.io/sse-gateway/listen/jenkins_blueocean net::ERR_INCOMPLETE_CHUNKED_ENCODING Warning: setState(...): Can only update a mounted or mounting component. This usually means you called setState() on an unmounted component. This is a no-op. Please check the code for the undefined component. Fetch complete: GET "https://ci.blueocean.io/blue/rest/search/?q=type:pipeline;excludedFromFlattening:jenkins.branch.MultiBranchProject". Warning: setState(...): Can only update a mounted or mounting component. This usually means you called setState() on an unmounted component. This is a no-op. Please check the code for the undefined component.
Seems that somewhere we try to do setState, which seems the cause of this issue.
tscherler did you try this on blueocean.io's Jenkins Design Language pipeline?
tscherler I tried this today and I got a similar problem where the state did not transition but there was an 404 in the console trying to fetch the log of the last node.
https://youtu.be/w9KbdgfKQjc I captured a screencast of it and may found the main cause.
The problem seem to be that the sse events are not getting delivered to the component and therefore we do not refetch the underlying data, leaving the component in a state of limbo.
tfennelly what can be the cause of
GET https://ci.blueocean.io/sse-gateway/listen/jenkins_blueocean net::ERR_INCOMPLETE_CHUNKED_ENCODING
I fixed some of the errors of the initial screenshot. especially "setState(...)..." see https://github.com/jenkinsci/blueocean-plugin/pull/350 by clearing the timeouts.
However I just observed again the failure on the io server. It really points to some problems with the sse. I need to consult tfennelly 
Further I cannot recall to have seen it locally failed once while developing on the karaoke mode, it could be specific to the setup of the io. The bad gateway at least have all the looks of it, but maybe michaelneale has an idea what could go on?
I think there may be other ways the events don't arrive (I am sure I have seen that with certain branch names in folders) - but in that case it always happens, not intermittent.
If you can't see it locally then I am not sure, it may be an issue with running through a proxy. If so, running a proxy locally (a little bit of work) may not be a bad idea. Otherwise it may be timing due to internet (I think chrome has tools to simulate lag, which may be worth trying).
Otherwise, book some time with tfennelly and he can probably spot it. that ERR_INCOMPLETE_CHUNKED_ENCODING does not happen locally, which is interesting (at least not that I have seen).
This wasn't tested locally. tickets based only on .io without local verification are not valid and kind of waste everyones time.
