When I click on the "Controllers" tab at the top of the MAAS UI it takes me to a list of different Rack Controllers that are present. When I click on one of them it takes me to the "Controller Summary and Network" page. When I click the back button in my browser I would expect it would take me back to the previous list of Rack Controllers that I had been looking at before but instead it takes me to Nodes tab page (MAAS home page).
