Vue.js: Hydration Timing Fixes Converge

Good day. It's July 3rd, and today's Vue core activity centers on one clear pattern: timing bugs in rendering and hydration.
The headline fix, PR 15035 from edison1105, addresses VNode anchor preservation during dynamic component hydration in the Vapor renderer. It's a broad change touching hydration, the renderer, component slots, and Vapor-to-VDOM interop. The core problem: async components, Suspense, and teleport content could leave…
The same author followed up with PR 15042, which adds a dev-mode warning when Vapor slots are invoked directly during hydration. This is a related boundary problem—direct slot invocation can grab server-rendered DOM outside the normal slot outlet path, causing a mismatch. Together, these two PRs show the Vapor…
The third piece, PR 15041 from ifer47, tackles a different but related timing issue: component function refs. Since an earlier fix, tracked in issue 14985, function ref callbacks stopped tracking dependencies—but they were still running before child template ref jobs completed, so exposed template refs came back…
The throughline here is sequencing: whether it's DOM anchors, slot outlets, or ref callbacks, several recent bugs trace back to…
