Webstory player - Rewind method doesn't reset the cover image

### Description

I'm trying to reset the state of the webstory player when reloading the page. I used the rewind method when finish page loading, that way I can start over the first story again.
However, If I was in a step different from the first one, after rewind it doesn't load the initial cover image.

### Reproduction Steps

1. Load webstory and navigate through the pages.
2. Stop navigation in a webstory page different from first one and reload the web page.
3. run player.rewind() to make the webstory to start again from the first webstory page.
Result: Initial cover image is not loading even if the player is now in the first webstory page.
