Still flaky
https://ci.chromium.org/p/chromium/builders/luci.chromium.try/mac_chromium_rel_ng/81910

Indeed. https://ci.chromium.org/p/chromium/builders/luci.chromium.try/mac_chromium_rel_ng/83148

As per https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=webkit_tests&tests=http/tests/inspector-protocol/page/page-lifecycleEvents.js , the link in the OP, it's still quite flaky.

Marking as flaky.
