Browser Back Button - Hamburger Disappears

I’m using the new Ionic 3+ lazy-loading, in an attempt to get url routes and a reasonable browser “back button” experience. Things seem to be working well, but I’m noticing an odd behavior. Each of my main side-menu items lands on a page with a hamburger menu in the header. Navigation is via setRoot(). When navigating through a few pages, the URLs change which is great. Clicking the browser back button does go back, but the hamburger menu is gone. What can I do to get the navbar to be the same, even on back button clicks?
