It doesn't look like this build failure is related.

Really interesting how these viewport test failures turn out to have entirely different root causes - see also bug 196236 and bug 197286.

There are others that are still waiting to be resolved: bug 196298, bug 195341, bug 181821.

It's not unusual that the tests in fast/viewport/ios are so flaky for different reasons than other tests that are generally about visual viewports, since the iOS tests tend to exercise the obscure nooks and crannies of ViewportConfiguration and friends, which only affect iOS.

I'll be investigating the other fast/viewport/ios failures (fast/viewport/ios/use-minimum-device-width-for-page-without-viewport-meta.html and fast/viewport/ios/*-width-viewport-after-changing-view-scale.html) next.
