This test appears to have recently become a flaky failure on the bots. It has come up as a false positive on EWS a few times in the last two days: https://bugs.webkit.org/buglist.cgi?quicksearch=fast%2Fviewport%2Fios%2Fdevice-width-viewport-after-changing-view-scale.html&list_id=4477417
I was able to reproduce the failure quickly with: run-webkit-tests --ios-simulator fast/viewport/ios/device-width-viewport-after-changing-view-scale.html --iter 25 --exit-after-n-failures 1
The earliest failure visible on the dashboard is from 1/21/2019, but the frequency of failures greatly increased on 2/3/2019.
