Since upgrading to 2.3.7 The Cart summary on /checkout/cart has stopped automatically expanding when arriving from"add to cart". If the page is refreshed or the quantity is updated the summary expands as expected. However, landing on the cart when the user adds to basket it's stuck. It was working on 2.3.4
I had used this code in module-checkout/view/frontend/web/template/summary/cart-items.
