Focus Keywords not working on Commerce Products

Description

The 'Focus Keyword' field is unavailable with the notice 'This feature is not available'.

The code suggests it should work and indeed, in earlier versions of commerce it did work.

Lines 170 to 173 in adf052d

    
           case 'craft\\commerce\\elements\\Product': 
        
           	$previewAction = $craft->getSecurity()->hashData( 
        
           		'commerce/products-preview/preview-product' 
        
           	);

Steps to reproduce

Add an SEO field to a product type where live preview is working

	case 'craft\\commerce\\elements\\Product':
	$previewAction = $craft->getSecurity()->hashData(
	'commerce/products-preview/preview-product'
	);
