* Preserve escaped block attributes when WooCommerce duplicates a product.

* WooCommerce passes a product description read from the database directly to
* wp_insert_post(), which expects slashed data. Without restoring that slash
* layer, escaped characters in block comment JSON (for example, \u003c in an
* SVG icon or \u002d in a preset CSS variable) lose their backslashes.
