"external/wpt/html/semantics/scripting-1/the-script-element/execution-timing/078.html" is flaky

Project Member Reported by chromium...@appspot.gserviceaccount.com, May 15 2018

Issue description

"external/wpt/html/semantics/scripting-1/the-script-element/execution-timing/078.html" is flaky.

This issue was created automatically by the chromium-try-flakes app. Please find the right owner to fix the respective test/step and assign this issue to them. If the step/test is infrastructure-related, please add Infra-Troopers label and change issue status to Untriaged. When done, please remove the issue from Sheriff Bug Queue by removing the Sheriff-Chromium label.

We have detected 3 recent flakes. List of all flakes can be found at https://chromium-try-flakes.appspot.com/all_flake_occurrences?key=ahVzfmNocm9taXVtLXRyeS1mbGFrZXNyXwsSBUZsYWtlIlRleHRlcm5hbC93cHQvaHRtbC9zZW1hbnRpY3Mvc2NyaXB0aW5nLTEvdGhlLXNjcmlwdC1lbGVtZW50L2V4ZWN1dGlvbi10aW1pbmcvMDc4Lmh0bWwM.

Flaky tests should be disabled within 30 minutes unless culprit CL is found and reverted. Please see more details here: https://sites.google.com/a/chromium.org/dev/developers/tree-sheriffs/sheriffing-bug-queues#triaging-auto-filed-flakiness-bugs
 
All 3 recent flakes are due to a timeout.  The test repros 10 out of 10 times when I try to run it locally.  The test passed 10 out of 10 times locally after specifying an artificially high timeout of 60 seconds.  I'll add the test to third_party/WebKit/LayoutTests/SlowTests.
BTW, looking at external/wpt/html/semantics/scripting-1/the-script-element/execution-timing/078.html I see:

    ...
    var t = async_test(undefined, { timeout: 10000 })
    ...
    setTimeout(t.step_func(function () {
        ...
    }), 5500);

Nothing more to be done here I think.
