Changing featured image from post preview no longer syncs to post edit screen

[westonruter]

If I click “Preview changes” in:

I am then opened in the Customizer where I can then select a featured image to preview:

However, upon clicking to go Back out of the Customizer, the featured image is not set in the metabox:

This used to work, so it may be a regression introduced in 4.8 or due to a change in the plugin itself.

This is the code in question:

wp-customize-posts/js/edit-post-preview-admin-featured-image.js

Lines 19 to 34 in 936b25e

	// Handle syncing settings from Customizer to edit post admin page.
	wp.customize.bind( 'settings-from-customizer', function( settings ) {
	var value, nonce, settingId = EditPostPreviewAdmin.getPostMetaSettingId( metaKey );
	if ( 'undefined' === typeof settings[ settingId ] ) {
	return;
	}
	value = settings[ settingId ];
	nonce = $( '#set_post_thumbnail_nonce' ).val();
	$( inputSelector ).val( value ).trigger( 'change' );
	if ( value > 0 ) {
	wp.media.featuredImage.set( value );
	} else {
	window.WPRemoveThumbnail( nonce );
	}
	} );
