Fixes #37971

The story fires events like story-content-loaded and story-page-visible even in prerender mode because the active page loads and is seen. However, the analytics config doesn't get loaded until the page changes the visibilityState, which can happen after 10s or more. Given that 10s after amp-analytics is initialized the buffer of events is cleared, these events get discarded, which we don't want to discard. Ideally these events are kept in the buffer for when the page becomes active, and at that point the events will be sent.

Can we add a test that tries to send events before visible and checks that triggerAnalyticsEvent is not called?
