Hey guys,
I have a viewport which has a left navigation with a bunch of links on it these links have listener events tied to them which onclick will load the url in the center panel I have placed in the viewport my issue is this after clicking a link and getting the content to load in the center panel if the user clicks back the page it self goes back the center panel's content doesn't go back? im trying to have it so that the page doesn't have to refresh every time a person clicks on a link on the left.

any idea how i can not break the back button and still have it so it only has the panel it self page go back?
