PR 15335, opened by edison1105, refactors hydration across nearly every rendering primitive in runtime-vapor. That includes conditional blocks, list rendering, components, slots, Teleport, Suspense, and transitions. The stated goal is improved reliability when server and client markup mismatch, while preserving DOM…
The theme here isn't multiple scattered fixes—it's one coordinated effort to harden hydration as a system. Anchor adoption, block handling, and fragment hydration are all called out as affected areas, which suggests the changes go deeper than a surface patch. When hydration logic is this centralized, a single bug…
For developers working with Vapor mode, the practical impact is this: expect more consistent behavior when server-rendered output doesn't perfectly match the client on first paint, whether that's due to conditional rendering, list diffing, or components wrapped in Suspense or Teleport. The PR…
