From 2e11af7fa400132af082ff35cbcdc9a2b8de1f99 Mon Sep 17 00:00:00 2001 From: Netzenbot Date: Tue, 31 Mar 2026 16:21:23 -0400 Subject: [PATCH] Disable DevToolsExtensionHostsPolicyTest.CantInspectBlockedHost on MSAN (#35097) Upstream Chromium test, stable upstream (0.9% flake rate over 30 days per LUCI Analysis). The test runs 10 eval retries with exponentially increasing timeouts (~10s total wall-clock time). Under MSAN instrumentation combined with Brave's additional DevTools startup overhead (chromium_src overrides, NTP/stats services), this exceeds the test's hardcoded 20-second timeout. The sibling test CantInspectBlockedSubdomainHost is already disabled in the upstream source for the same reason.
