This is a rare failure on post-commit bots.

-PASS Constructed GamepadEvent timestamp should be high resolution and have the same time origin as performance.now() 
+FAIL Constructed GamepadEvent timestamp should be high resolution and have the same time origin as performance.now() undefined is not a constructor (evaluating 'new window[eventType]('test')')

Looks like a garbage collection bug?
