Short description of issue

Cart drawer shows page under bottom bar + background scroll (Safari + IOS 26)

Link to Shopify Store

Nuvio - Nuvio

Reproduction steps

On an iPhone running iOS 26, open the site in Safari, navigate to any product detail page (PDP), and tap Add to cart to open the cart drawer.

Additional info

Theme: custom (Dawn-based)

Tried: position: fixed + background scroll lock on open/close, 100dvh/100svh/100lvh, env(safe-area-inset-bottom), overscroll-behavior: contain, and a bottom “guard” element.

Result: background no longer scrolls, but the lower edge still reveals the page when Safari’s dynamic toolbar slides in/out.

Same exact problem here, and from what I have seen, many other ecommerce brands using Shopify have this issue aswell. Has anyone found a solution?
