QA failure in qa/specs/features/ee/browser_ui/2_plan/iterations/create_group_iteration_spec.rb in Update job

Summary

Staging Orchestrated Update job fails in qa/specs/features/ee/browser_ui/2_plan/iterations/create_group_iteration_spec.rb with issue that was fixed in #347082 (closed).

The same test passes in ee:instance-parallel 2/5 job in the same pipeline:

Need to investigate why spec fails in Test::Omnibus::Update scenario.

Possible fixes

Needs further investigation why specifically in Test::Omnibus::Update scenario create_group_iteration_spec still fails.
