Copied from the original issue: csells/go_router#389

In the books example, you have a navigation rail down the left side of the page. I am trying to replicate this functionality with permanent sidebar navigation and was using this example as a reference. I have realised in testing however that this rail is not persistent and is built again on every page load (not the expected behaviour). As a result, if you pay close attention to the InkWell effect on the navigation buttons, when you click them they start the animation however cancel early when the page is loaded and the new version of the navigation rail loads.
