Only throttle DOM timers if they change CSS properties that cannot cause non-descendant elements to become visible. For example, a DOM timer may change the height of an element that is outside the viewport. However, changing its height may causes elements inside the viewport to move. As such, we should NOT throttle such DOM timer.
