Hi.  
When we change page in Discourse, these are the apparent steps:

1. We click on the link
2. The current content disappears and the loader appears
3. The URL is updated and the new content appears

This is slightly different when we go from a page to the home, as the URL is changed to the home URL when the current content disappears, and not when the new content appears.

My goal is to have a script that is executed as soon as we click any page link on Discourse.  
`api.onPageChange` won’t fit in this case since the code is executed quite at the same time the new page content is loaded.

Is there a Discourse method for that? I look at the event triggers but didn’t find any one corresponding to what I need.
