Reproduce the issue with the shown TabControl configured with prism:RegionManager.RegionName="MainRegion", then trace the UI flow after _regionManager.RequestNavigate("MainRegion", obj). Start by examining the TabControl and Prism region interaction; done means the requested tab is selected on the first click, with a regression test or documented verification covering that behavior.
