Description

Block templates are connected to specific URL paths and are not updated if the original post's post_name is updated. We might want to consider linking to the short URL (canonical) as a reference instead.

Step-by-step reproduction instructions

1. Create a post "Test Post A" and publish. Observe that with permalinks enabled, the post_name is test-post-a.
2. Create a custom block template for the previous post and add some additional blocks to the template to help verify this custom template is loaded on the front end. After saving the template, view the post on the frontend and it should be using the custom template.
3. Edit the "Test Post A" post and change the post_name value to something different.
4. View the post on the frontend and you'll see that it is no longer using the custom template that was created.
