Changeset 60003 for trunk/src/wp-includes/block-editor.php

Message:

Editor: Support site preview mode for the Site Editor.

This allows the Site Editor to load a preview of the site as an IFRAME_REQUEST by checking for a wp_site_preview query param. By setting the IFRAME_REQUEST constant when loading the preview, the site's admin bar and some third party plugin overlays will not be shown in the preview.

Props wildworks, joemcgill, peterwilsoncc, presstoke, mamaduka, johnbillion, faisal03.
Fixes #63076.
