* Fix html in preview of product titles
Previously the html wasn't rendered in the preview for product titles.
This renders the html.
* Update test snapshot
* Also decode html for featured preview name.
* Un-escape HTML for featured post title render
* Add placeholder image for product preview
This adds the designated placeholder image url from settings into the
wcSettings global for the blocks to use. Then uses the placeholder url
when a product doesn't have any images.
* Updated based on review notes
Using `$block_settings` instead of `$settings`
Using '' alt tag
Updated snapshot
* Add the placeholder global to test that it passes through to the preview
* Add a second block, for “products by category”
* Fetch products in the given category, when attributes change
* Display the resulting products
* Style the product preview
* Create utils folder, move shared attributes
* Move getQuery to shared utils folder
* Create a helper function to get the shortcode string
* Support the menu_order setting
