Reproduce the navigation flow in the My TDM Plans interface, starting from the Deleted TDM Plans tab and opening a deleted draft or snapshot. Trace the route and tab state used by the browser Back action; done means Back returns to the Deleted TDM Plans tab, with a regression test covering the flow if the existing frontend test structure supports it.
