Reviewed by Sam Sneddon.
The test imported/w3c/web-platform-tests/workers/SharedWorkerPerformanceNow.html
is flaky because it asserts that performance.now() must be strictly greater
than 0.
However, due to WebKit's 1ms timer precision (Performance.cpp:72), if the
SharedWorker
calls performance.now() within ~0.5ms of creation, the time rounds down to 0ms.
Performance.now() returning 0 is valid when called at or very
close to the time origin. The test should accept 0 as a valid value.
Changed assertion from assert_greater_than(results[3], 0, ...) to
assert_greater_than_equal(results[3], 0, ...) on line 19.
