311602 2026-04-06 16:44:36 -0700 [Quirk] invideo.io: add a window.chrome object to bypass the code sniffing. 2026-04-08 17:40:44 -0700 1 1 1 Unclassified WebKit New Bugs WebKit Nightly Build Unspecified Unspecified RESOLVED FIXED http://invideo.io InRadar P2 Normal --- 1 karlcow karlcow webkit-bug-importer oldest_to_newest 2197422 0 karlcow 2026-04-06 16:44:36 -0700 There is a double block on Safari: 1. !!window.chrome (line 1798) — a property-based sniff that excludes all non-Chromium browsers 2. ["safari"].includes(browserName) (line 1921) — an explicit UA-based Safari exclusion via dhe(), used to prevent Safari from passing even if it supports the required Web APIs Safari actually supports both WebGL2 and SharedArrayBuffer (with proper COOP/COEP headers). The site's playback engine likely depends on Chromium-specific behavior or simply never tested on Safari/WebKit. The block is browser-sniffing, not feature-detection — Safari is excluded by name and by the absence of window.chrome, not because it lacks the required capabilities. There is an outreach radar too. rdar://172352516 The User-Agent override has been done on the side of the Safari code. This part will address the window.chrome object faking in the WebKit Code.
