This PR fixes #271 by adding a new
whenActivatedutility and using it to defer all of theonXXX()metric functions. It also tweaks thegetVisibilityWatcher()logic to better handle prerendering cases (which always happens when thevisibilityStateis "hidden", and are thus tricky to get right).Note: make sure to look at the diff ignoring whitespace, otherwise it looks like much more changed than did.
