[Bug]: Mobile Cart Drawer - Checkout button hidden / drawer unscrollable on mobile 360px - Dawn 15.0.0

Describe the current behavior

On mobile viewport 360x800, after adding product to cart, the cart drawer opens. Subtotal is visible but the Checkout button is hidden below the fold and the drawer cannot be scrolled.

cart-drawer has overflow: hidden / max-height issue, so user cannot reach checkout.

Reproduced on:

• Official Shopify demo: https://dawn-theme.myshopify.com/products/the-collection-snowboard-liquid
• My dev store: https://dm-furniture-jogja-bug.myshopify.com

Describe the expected behavior

Cart drawer should be scrollable on mobile and Checkout button must always be reachable. Should use overflow-y: auto with proper max-height: 100dvh.

Version information

• Dawn Version: 15.0.0
• Chrome Version: 126.0.6478.122 Mobile
• Android Version: 13
• Viewport: 360x800

Possible solution

Change .cart-drawer container to:

.cart-drawer__inner { overflow-y: auto; max-height: 100dvh; }

Reproduce the cart drawer at 360x800 on the linked Dawn demo, then inspect the cart-drawer and .cart-drawer__inner styles. Verify the drawer can scroll and the Checkout button remains reachable after applying the proposed overflow and viewport-height behavior.
