Description

When starting with a visibilityState prerender on my story, if I quickly set it to visible, the event StoryPageVisible triggers for page 0.
If I wait for a few sec (lets say 15s), then set visibilityState to visible, it does not trigger.

Reproduction Steps

Here is an example : https://vhmjjq.csb.app/

• Open your console and filter the network calls with eventType=storyPageVisible to see the analytics calls.
• You have a timer to try quickly, or after 15s, and see the difference.
