Current behavior: In an Ionic 3.5.0 app with lazy loading, the back button is missing after following a subpage deeplink or reloading. Reproducible in the simple-tabs navigation test.

Expected behavior: The back button to be shown.

Steps to reproduce:

1. Clone the ionic-angular repo and npm install.
2. Run gulp e2e.watch --folder nav/simple-tabs.
3. In “Page One”, click the “Go to next page” button. “Page Two” is opened and the back button is shown.
4. Reload “Page Two”. The back button is missing.

@danbucholtz this doesn’t appear to be fixed in ionic 3.9.2.

I’m using defaultHistory but do not get any back button when going to a page via its segment.

Yep, looks like there is a bug. I’ll take a look.

Thanks, Dan
