Adds a middleware to `apiFetch` to set the theme for the preview.
This adds awp_theme_preview
URL parameter to API requests from the Site Editor, so they also respond as if the theme is set to the value of the parameter.Source

// Don't allow non-admins to preview themes.
if ( ! current_user_can( 'switch_themes' ) ) {
return;

wp_add_inline_script(
'wp-api-fetch',
sprintf(
'wp.apiFetch.use( wp.apiFetch.createThemePreviewMiddleware( %s ) );',
wp_json_encode( sanitize_text_field( wp_unslash( $_GET['wp_theme_preview'] ) ) )
),
