 == Summary
 When deleting a user from the WordPress admin, the confirmation page
 (`/wp-admin/users.php?action=delete&user=<ID>`) **never finishes loading**
 in Chromium-based browsers (Chrome, Edge, Brave, Opera), or takes an
 extremely long time to do so. When loading does eventually complete, **the
 “Confirm Deletion” button is missing from the rendered page**, making it
 impossible for the administrator to complete the action.

 The same flow works correctly and instantly in Firefox.

 No JavaScript error is logged in the DevTools console.


 == Steps to reproduce
 1. Log in to `/wp-admin` as an Administrator.
 2. Go to **Users → All Users**.
 3. Click **Delete** under a user (or use the **Delete** bulk action).
 4. The browser navigates to the deletion confirmation page.
 5. Wait.


 == Expected behavior
 The confirmation page loads quickly and displays the **Confirm Deletion**
 button (as it does in Firefox).


 == Actual behavior
 - The page load spinner runs indefinitely, or for tens of seconds /
 minutes.
 - If the page eventually finishes loading, the **Confirm Deletion** button
 is not present in the DOM.
 - The console reports no error.
