Doing the first edit on a freshly duplicated page doesn't show the Revisions field

Why this is a good first issue

Behavioral expectations for revisions on duplicated pages are unclear and require deeper investigation.

AI Summary

The issue involves unexpected behavior where revisions don't appear after the first edit on a duplicated page. The root cause appears deeper than initial code inspection suggests, requiring investigation into post duplication behavior and revision tracking. Maintainers indicate this may involve architectural decisions about how duplicated content should handle revisions.

Issue Description

Issue debugged with @tyxla.

When duplicating a page, no revision is created by default. That means that when saving the first edit, the Revisions field doesn't show up. It's only displayed once the second edit is saved.

Step-by-step reproduction instructions

Go to Appearance > Editor > Pages.
Duplicate one page.
Make one edit and save.
In the Page panel, notice there is no Revisions field.
Make a second edit and save again.
Notice the Revisions field is visible.

Expected result: in step 4, the revisions field should already be visible.
