[iOS Simulator] compositing/overflow/dynamic-composited-scrolling-status.html failing
Need to look at this one.
Marked as failing in r194797.
It looks like that this test case only fails at iOS simulator WK2 nowadays. Move it to WK2 only.
Committed r204752: <http://trac.webkit.org/changeset/204752>
When gardening for iOS testing, it turns out that this only fails on iOS Simulator WK2. Changing expectations to reflect this <https://trac.webkit.org/r217740>.
