Reported from some users of twitter.com and first noted in @firt's writeup, https://medium.com/@firt/iphone-11-ipados-and-ios-13-for-pwas-and-web-development-5d5d9071cc49

When using an installed PWA, the In-App browser when you link to external scopes has a bug, where the back button to your PWA shows “◀Untitled” and not the actual PWA’s name or short name (see image below)

Thanks for filing, I believe the issue is occurring outside of WebKit. Apple internal see rdar://54220296.
