Interactivity Router does not update content with back/forward after reload #70500
Description
Description
The Interactivity client-side router does not update content when using the back/forward browser navigations after reloading a page that has been navigated to via client-side routing. The URL changes, the scroll position is restored, but the content remains the same. I'd expect either the client-side router to not activate or the content to be updated to show the correct content for the URL.
Step-by-step reproduction instructions
Via WordPress Playground, using core/query enhanced pagination:
- Open this blueprint
- On the homepage, click the next page pagination link a couple of times.
- Right click → Reload frame (or equivalent).
- Right click → Back (or equivalent).
- Notice how the list of blog posts has not updated.
Via a normal installation:
- Generate many posts, i.e.
wp post generate. - Create/edit a template to display posts with pagination via the
core/queryblock. Ensure Full page reload is off. - Go to the page that uses said template.
- Click the next page pagination link a couple of times.
- Reload the page.
- Hit the back browser button.
- Notice how the list of blog posts has not updated.
