[iOS] Search Keyboard persists between sessions

Issue: The search keyboard remains on screen between sessions in the app.

Details to reproduce: From the feed, tap the mag glass and begin a search but don’t tap a result. Close the app. Open the app again to the feed and the search keyboard is still there obscuring half the feed and, importantly, the navigation bar. Only way to get rid of it is to tap on a feed entry and go back again.

OS: 12.1.1
