third_party/WebKit/LayoutTests/imported/web-platform-tests/dom/events/Event-propagation-expected.txt

-This is a testharness.js-based test.
-PASS Newly-created Event 
-PASS After stopPropagation() 
-FAIL Reinitialized after stopPropagation() assert_equals: Propagation flag expected true but got false
