@simonhong mind checking https://staging.ci.brave.com/job/brave-browser-build-pr/job/pr3251_show_bookmark_bar_on_ntp_by_default_0.69.x/1/execution/node/645/log/? Looks like it failed during npm run test -- brave_browser_tests Release --output brave_browser_tests.xml:

Looks like #3274 passed without any issues. Going to see if a restart clears up the issue 👍
