From my debugging and googling, the latest version of Tabbable that is 5.3.0 (and onwards) needs some changes to the Modal/Wizard components in Patternfly4 to be able to support tests.
Specifically this: https://github.com/focus-trap/tabbable#testing-in-jsdom
Modal currently has the prop disableFocusTrap that can be set to false and that lets us work around the issue without ever activating the trap. I spoke to folks on PF4 slack and they lock the version of FocusTrap but Focustrap brings in the latest 5.x.x tabbable causing the test failures.
There's an open PF4 issue around this: https://github.com/patternfly/patternfly-react/issues/7288
Created from redmine issue https://projects.theforeman.org/issues/34802
Upstream bug assigned to None
This will need to be cherry-picked to 6.11 to resolve the pipeline errors seen here: https://master-jenkins-csb-satellite-delivery.apps.ocp4.prod.psi.redhat.com/blue/organizations/jenkins/sat6-unit-test-katello/detail/sat6-unit-test-katello/722/pipeline
Moving this bug to POST for triage into Satellite since the upstream issue https://projects.theforeman.org/issues/34802 has been resolved.
