Every build that runs webkit_layout_tests, for example this one:
https://ci.chromium.org/buildbot/tryserver.chromium.linux/linux_chromium_rel_ng/602034

is failing these three layout tests:
* http/tests/devtools/sources/debugger-async/async-await/async-pause-on-exception.js
* http/tests/devtools/sources/debugger-pause/debugger-pause-on-exception.js
* http/tests/devtools/sources/debugger-pause/debugger-pause-on-promise-rejection.js
 
Looking at the layout test results:
https://storage.googleapis.com/chromium-layout-test-archives/linux_chromium_rel_ng/602034/layout-test-results/results.html

they seem to be failing just because there's additional whitespace in the results:
