This test needs 5 seconds to finish, and timeout was set to 6 seconds. I took some examples from failed tests, and all failure cases were due to timeout. Probably, we need to adjust timeout values in the test. Will send a CL to ksakamoto for a review.

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/6f18ed2cbb970994851aee07953b00a4ef6c7e6b commit 6f18ed2cbb970994851aee07953b00a4ef6c7e6b Author: Takashi Toyoshima <toyoshim@chromium.org> Date: Sat Mar 10 02:15:25 2018 WebFonts: adjust test timing to mitigate flakiness Current slow-loading.html requires at least 5 seconds to finish. This may easily exceeds 6 seconds timeout of LayoutTests. To stabilize the test, let me change the result check timing from 5 seconds to 4 seconds.
