Thanks for this, but I think you need to find someone to CC and/or a component to set to avoid this bug to go unnoticed forever...

From https://chromium.googlesource.com/chromium/src/+/abab7b8784d712bb28f628d43db59eefb0bac8ec which is a part of the blamelist of https://luci-milo.appspot.com/buildbot/chromium.webkit/WebKit%20Mac10.11%20%28dbg%29/10298 I can see sheriff instructions, so I'm adding dgrogan@chromium.org, joysyu@google.com to CC

It is failing on these bots too:
* WebKit Win7 (dbg) Build https://luci-milo.appspot.com/buildbot/chromium.webkit/WebKit%20Win7%20%28dbg%29/11378
* WebKit Linux Trusty (dbg) https://luci-milo.appspot.com/buildbot/chromium.webkit/WebKit%20Linux%20Trusty%20%28dbg%29/5702

I will submit a CL for a wider expectation.

Mark external/wpt/css/css-tables-3/table-model-fixup-2.html as failing on Win and Linux

In addition to Mac, which was previously set. Also make the bug reference point at the right
bug.

Removing regression -- this has failed since it was introduced into the tree. Maybe it's flaky? Otherwise the initial import would have set an -expected.txt.
