Offscreen Async animated Element causes 60fps rendering on main thread
+++ This bug was initially created as a clone of Bug #1104151 +++ When Async animated Element's does not have related DisplayItem, the element requests 60fps rendering on main thread. This typically seems to happen when the Element is off screen. Throttling animation failed. AnimationPlayerCollection::CanThrottleAnimation() return false because FrameLayerBuilder::GetDedicatedLayer() return nullptr. http://dxr.mozilla.org/mozilla-central/source/layout/style/AnimationCommon.cpp#804 http://dxr.mozilla.org/mozilla-central/source/layout/base/FrameLayerBuilder.cpp#4138
When this problem happens, Async Animation error log printout nothing about it.
See Bug 1104151 about the symptom that happened on b2g.
