        <pre>The test svg/in-html/by-reference.html is a flaky failure on El Capitan and Sierra testers according to the dashboard.

<a href="https://build.webkit.org/results/Apple%20Sierra%20Release%20WK2%20(Tests)/r220972%20(3728)/results.html">https://build.webkit.org/results/Apple%20Sierra%20Release%20WK2%20(Tests)/r220972%20(3728)/results.html</a>

I was able to reproduce the failure with run-webkit-tests --no-retry-failures --iterations=100 svg/in-html/by-reference.html consistently after revision r220052. The Failures did not occur before this revision:
