What?
Epic: #56803
This PR ensures the first page is cached using the vDOM tree generated during hydration.
Why?
As the
@wordpress/interactivity-router
module is loaded asynchronously, it currently caches the first page traversing the current DOM, which interactive blocks could have modified. This PR prevents that issue by using the same vDOM hydrated.How?
Exposing from the
@wordpress/interactivity
module aWeakMap
calledinitialVdom
, relating the generated vDOM trees with the root node where they are hydrated. ThisinitialVdom
weak map is exposed from a function namedprivate APIs
, which also returns other APIs meant to only be used internally.Testing Instructions
