imported/w3c/web-platform-tests/html/dom/dynamic-markup-insertion/opening-the-input-stream/011.html flaky on macOS High Sierra WK2 but is timing out far more than running normally.

This does not appear to be a recent regression but has begun to be more consistent.

The test generally times out at ~35 seconds but will spike up to ~50-70 seconds.
