Control the IntensiveWakeUpThrottling feature

When enabled, the IntensiveWakeUpThrottling feature causes Javascript timers in background tabs to be aggressively throttled and coalesced, running no more than once per minute after a page was backgrounded for 5 minutes or more.

This feature is a web standards compliant feature, but it may break functionality on some websites by causing certain actions to be delayed by up to a minute. However, it results in significant CPU and battery savings when enabled. For more information, see https://bit.ly/30b1XR4.

If you enable this policy, the feature is force enabled, and users can't override this setting.
If you disable this policy, the feature is force disabled, and users can't override this setting.
If you don't configure this policy, the feature is controlled by its own internal logic. Users can manually configure this setting.

The policy is applied per renderer process, with the most recent value of the policy setting in force when a renderer process starts. A full restart is required to ensure that all the loaded tabs receive a consistent policy setting. It's harmless for processes to be running with different values of this policy.
