 Thanks, @costdev!

 == Test Report

 [https://core.trac.wordpress.org/attachment/ticket/52422/52422.refresh-of-
 PR-1333.diff Patch 52422 (PR 1333 refresh via @costdev)] 👍🏻

 === Env
 * WordPress 6.1-alpha-53344-src
 * Safari 15.4
 * Chrome 101.0.4951.54
 * macOS 12.3.1 (Monterey)
 * Theme: Twenty Twenty-Two
 * Gutenberg DISABLED 🔴

 === Steps to Test
 1. Ensure permalink structure is set to "Post name" in ''Settings >
 Permalinks''.
 1. Under ''Posts > Add New'' create a new post with the title "Test Post"
 and **Publish**.
 1. In another tab, verify that the post is published at `<your site url
 >/test-post/`. ✅
 1. Navigate to ''Posts > Add New'' and create another new post with the
 title "Test Post 2", and click **Save draft** (DO NOT click **Publish**).
 1. Find the "Permalink" metabox on the right-hand side of the post editor
 and update the "URL Slug" to `test-post` by removing the `-2` -- this will
 match the slug of the first new post. Click **Save draft** again (DO NOT
 click **Publish**).
 1. In the second tab, refresh the page at `<your site url>/test-post/`.
 1. Observe that the post title displayed is now "Test Post 2", indicating
 that the draft post is overriding the original post's slug. ❌
 1. Open the page in Private Browsing/Incognito mode and observe that a 404
 error (not found) is returned, as the draft post is not published. ❌
 1. Apply patch. 🛠
 1. From the main Posts page, "Move to Trash" and "Delete Permanently" both
 "Test Post" and "Test Post 2".
 1. Repeat Steps 2 through 5.
 1. Observe that the "Permalink" metabox in the post editor refreshes the
 "VIEW POST" link to `<your site url>/test-post-2/`. ✅
 1. In the second tab, refresh the page at `<your site url>/test-post/`.
 1. Observe that the post title remains "Test Post", indicating the draft
 has not overridden the published post's slug. ✅
 1. In Private Browsing/Incognito, observe that the originally published
 post is displayed (404 error has been mitigated).

 === Expected Results (✅)
 - The patch corrects the identified issue.

 === Additional Notes
 - The above reproduction steps do not apply to Pages, but only to Posts.
 Pages seem unaffected by this issue (i.e. a draft page does not override
 an existing published page slug).
