On trybot win_chromium_rel_ng and win_chromium_x64_rel_ng, the test sometimes fails due to timeout.

My run with patch fails on this test 3 times and that without patch fails twice. I also see several different CLs
fail this test on win_chromium_rel_ng. So I think this is probably a problem of the test itself.
