            Bug ID: 212839
           Summary: history.replaceState(..) results in title being
                    removed from history entry
           Product: WebKit
           Version: Safari 13
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: History
          Assignee: webkit-unassigned at lists.webkit.org

Code sample useful for reproducing the bug

Please see attached sample demonstrating the bug.
Make sure test2.html is loaded from an HTTP server - it won't work from file://

1) Load test2.html from an HTTP server
2) Click About and Contact Us in the menu
3) Long-click on the Back button in Safari.
   Notice how none of the history items have any titles (see Screenshot-bug.png)

Now disable the code triggering the bug (see Screenshot-code.png) and re-run the test. Notice how all history entries have titles now (see Screenshot-working.png).

This is a major annoyance when working with Single Page Applications and routing. Being able to update state associated with the current page, e.g. before "navigating" to the next page as in my example, makes perfect sense. Losing the context information the title provides will confuse many users.

The sample works fine in latest Chrome, latest Firefox, latest Edge based on Chromium, old MS Edge, and IE11.
The sample fails on Safari 13.1, 12.1, and 11.1.
