Until we have both monotonic and scroll-driven animations both accelerated in the remote layer tree, we need to ensure the different accelerated approaches can coexist and this means that in the case where a monotonic and a scroll-driven animation both target the same underlying property, we need to disable accelerated animations altogether.
