Given the new policy for experimental features and given that the
behavior has already been enabled for all tests for 2 weeks now, we
should either 1) remove the flag from the experimental category and
enable by default or 2) disable it for tests and enable it on a per-test
basis using headers.
I'm proposing the former in https://bugs.webkit.org/show_bug.cgi?id=189472
Note that enabling the flag is a big behavior change that might impact
users but at the same time will fix an old compatibility issue between
WebKit (non-standard behavior) VS Chromium/Gecko/Edge (CSSOMView behavior).
