This tests that

Is this necessary?

contentVisibilityDidChange? didContentVisibilityChange sounds like a question.

Use a switch so that you get warnings from the complier?

I think "notify" would be a better term to use.

Normally we'd say "startObservingFoo/stopObservingFoo".

Event is a bit of an overloaded term. Maybe OK here.

I think you can remove the "Did" from all these. Maybe use the past tense:
Event::InstalledDOMTimer.
