This should not be needed anymore. We no longer need to "ack" an epoch, since there's no epoch. Make the logic to trigger a paint and request composite a bit more generic. That doesn't change behavior right now, because our visibility state is tied to mRenderLayers, but without this change setting renderLayers = true on a display: none iframe will trigger a useless paint after bug 1847584.
