When using the tabs theme in a v4 project, I noticed that when navigating past the root level of the tab, the history of that tab is lost when switching between tabs.
I also noticed that this is the case on the core-update (v4) branch of the Ionic conference app demo. https://github.com/ionic-team/ionic-conference-app
Is tab history a feature that will be lost switching to angular routing from push/pop style nav? Or will is there a way to maintain tab history for each tab with angular routing?
