I cloud reproduce the failure locally on an opt build. Will try to catch what's going on there.

So the failure happens when we haven't received BrowserChild::mTopLevelViewportVisibleRectInBrowserCoords from APZ.
Our animation code has an optimization that we skip restyling/painting where the animation's target element is scrolled out. If the target element is in an OOP iframe, we use the BrowserChild::mTopLevelViewportVisibleRectInBrowserCoords to see whether the iframe is scrolled out (or clipped out) by ancestor viewports. But if we haven't received the mTopLevelViewportVisibleRectInBrowserCoords from APZ, the corresponding function, BrowserChild::GetTopLevelViewportVisibleRectInBrowserCoords returns an empty rectangle, thus we incorrectly consider the element is scrolled out, then we fail to paint the animation, thus we fail a sanity check in animation_utils.js.

With this change we no longer incorrectly consider there is no visible rect for
the OOP iframe where we haven't yet received the rectangle from APZ.
Pushed by hikezoe.birchill@mozilla.com: https://hg.mozilla.org/integration/autoland/rev/5e0d86ff0ab9 Make GetFrameVisibleRectOnScreen return Nothing() if we haven't received OOP iframe's transformed rectangle from APZ. r=botond
