We recommend opening the site in Chrome.") The modal does not appear in Chrome. The login QR/account form renders behind the modal, so the page is otherwise functional. this is purely a user-agent gate against non-Chrome browsers. Steps to reproduce: 1. Open Safari. 2. Navigate to https://mms.pinduoduo.com/ 3. Observe the redirect to the login page and the "not Chrome" modal. Expected: the login page is usable without a "use Chrome" interstitial. Actual: a modal blocks the page recommending Chrome. 2225221 1 karlcow 2026-06-30 01:49:48 -0700 <rdar://180551491> 2225225 2 karlcow 2026-06-30 02:09:03 -0700 Pull request: https://github.com/WebKit/WebKit/pull/68302 2225919 3 ews-feeder 2026-07-01 15:31:56 -0700 Committed 316336@main (988c6a663e9a): <https://commits.webkit.org/316336@main> Reviewed commits have been landed.
