Some page object self tests in the new UI test framework seem to fail rather frequently, especially on Jenkins, namely

info.magnolia.testframework.selftest.ContentAppSelfTest#unselectRowByPath

info.magnolia.testframework.selftest.MediaEditorSelfTest#mediaEditorPerformsAction

info.magnolia.testframework.selftest.AlertNotificationSelfTest#alertConfirmAndNotification

Increasing the wait timeout for some possibly long actions, such as when hitting the "save" or "commit" button in forms or alerts only partially helps.

Locally, I observed that sometimes such tests fail the first time but pass the second time around, if one repeats them. Would be nice to have a @RetryOnFailure annotation also for JUnit5. There actually is a native @Repeated one but it doesn't take failures into account.

Also tried some 3rd party JUnit extensions as suggested here https://www.swtestacademy.com/junit-5-how-to-repeat-failed-test/ but sadly they didn't work that great.
