Prerequisites

• I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• The issue still exists against the latest stable version of Elementor.

Description

Elementor provides a "Preview Changes" button to preview changes made in a page before pubhlishing it. When using this feature on the page defined as Homepage in Wordpress (->Settings->Reading: A static page: Homepage), the changes made are not shown in the preview browser window. This effect does not happen for other pages. On these pages, the preview browser window correctly shows the changes made.

Steps to reproduce

• Create wordpress db.
• Copy wordpress folder to htdocs folder.
• Install web page.
• Run updates if provided by Wordpress backend
• Configure Wordpress backend:
  a) Perma links: post name
  b) Date format: d/m/Y
  c) Time format: H:i
• Create and publish 3 pages, e.g. start, contact and blog.
• Assign start and blog in the Wordpress backend under ->Settings->Reading: A static page.
• Delete all plug-ins; install elementor and activate it.
• Configure Elementor: Show editing handles.
• Edit start page ("Homepage") with elementor and preview changes -> no changes are shown in the preview window.
• Edit contact page with elementor and preview changes -> changes are shown correctly in the preview window.

Isolating the problem

• This bug happens with only Elementor plugin active.
• This bug happens with a default WordPress theme active.
• I can reproduce this bug consistently using the steps above.
