Changing Title changes URL

[RBM7777]

Having the URL change whenever the a page or post Title changes is a major hazard. You can say "works as designed"; but this is not a good design - people can edit a Title and get an unexpected URL change, breaking links and requiring re-direction of the accidental URL. At a minimum, upon hitting the Update button, user should be warned that URL is about to change - and required to approve this before page is re-published.

Hi there, welcome to WordPress Trac! Thanks for the ticket.

In my testing, the slug only changes on title edit for drafts, not for published posts. Changing it for published posts was previously discussed in #35352 but decided against and never implemented, exactly to avoid breaking existing links.

Does the issue still happen with all plugins disabled and a default theme (Twenty Twenty-Two) activated? Could you provide the steps to reproduce it on a clean install?
