Created attachment 472674 [details] Crash Hello, Starting from iOS 18, we've experiencing a major regression crashing our Shopify theme. I have completely been unable to isolate it, so it might be due to a lot of conditions causing the problem. It seems to happen when there are nested overflowing elements. To reproduce the issue on iOS 18 you must: 1. Open this page: https://focal-theme-carbon.myshopify.com/ 2. Add at least 8 different products to the cart to cause an overflow on the cart drawer. 3. Open the drawer, scroll, and close the drawer, which will cause first a kind of page reload, and if you repeat the process, will crash the whole browser. I have attached a video showing the crash.

Thank you for the report. I cannot reproduce this with a newer WebKit build, perhaps this is already fixed. Could you please attach the crash log? https://developer.apple.com/documentation/xcode/acquiring-crash-reports-and-diagnostic-logs
