The WPT test scroll-animations/view-timelines/fieldset-source.html is a failure. It mistakenly is marked as PASS macOS at the moment because the failure happen within a forEach() callback, but it fails there too, not just on iOS.

The issue appears that in the test we are using getBoundingClientRect() which accounts for padding and border, but the measurements we're taking in ViewTimeline::cacheCurrentTime() do not account for that, so we're off by 6 pixels (2 pixels of padding and 4 pixels of border).
