layout-animations
This policy controls the ability of a document to perform animations that require updates to layout, rather than simply repaints, which are typically cheaper and allow for smoother animations. So-called 'layout animations' can require significant CPU and often cannot be rendered smoothly.
If a document is disallowed from performing layout animations by this policy, only the inital and final states of the animation will be rendered.
