Throttle Javascript timers in background

When enabled this feature causes Javascript timers in background tabs to be aggressively throttled and coalesced, running no more than once per minute after a page has been backgrounded for 5 minutes or more.This 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. – Mac, Windows

this is an additional feature to the optimizations that Edge already has, or features such as sleeping tabs.
