which is caused by reporting plugin logging after Kibana stops.
There are 2 problems:

• Reporting plugin doesn't interrupt the installation process when Kibana stopped
• Reporting runs installation when unnecessary.

I fixed the problem by disabling the reporting plugin in this specific case, but it's rather a workaround.
@elastic/kibana-reporting-services is it possible to install a browser in dev mode by a request?
if no, @elastic/kibana-operations should we disable the reporting plugin by default in all the integration tests with oss: false? tbh, I'd like to avoid that because it means dev and test configuration diverge.

It seems this is no longer an issue. I am closing this to take it off our tracker.
