What?

Why?

  • When a reload action happens after going through the pagination of a query loop, navigating backwards or forwards renders the same cached page regardless of the URL.
  • Expected behaviour is for the correct page in the pagination to render

How?

  • Removed the prefetch call made in the navigate action

Testing Instructions

  • Generate many posts, i.e. wp post generate.
  • Create/edit a template to display posts with pagination via the core/query block. 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 updated.

👋 Hi, @Vrishabhsk, thanks for the PR! The actions.prefetch() call in navigate() is required, though; some of the e2e tests were failing with that change.

I created #75927, which supersedes this one. You also appear there as a contributor. 🙂
