### Handle out of stock product visibility setting in All Products block (#3859)
1. Add All products block to a page.
2. Mark one product as `Out of stock`, and one as `On back order`.
3. Select WC > Settings > Products > Inventory > Hide out of stock items from the catalog.
4. Go to the frontend and view the page with the All products block on it. Verify that the `Out of stock` product is not showing, but the `On back order` product is visible.
## Feature plugin only
### Update Panel component class names to follow guidelines (#3860)
1. Go to a page with the Cart and/or Checkout block inserted and verify there are no visual regressions. Pay special attention to elements that use the Panel component (Coupon code, shipping selector, order summary, etc).
2. Verify there is no regressions in the Stripe payment method card icons (you will need the [Stripe Payment Method extension](https://woocommerce.com/products/stripe/) installed).
### Remove shadows from text buttons and gradient background from selects in some themes (#3846)
