Depends on: - #28317 - #28320 --- Changes the behavior of the JSX runtime to pass through `ref` as a normal prop, rather than plucking it from the props object and storing on the element. This is a breaking change since it changes the type of the receiving component. However, most code is unaffected since it's unlikely that a component would have attempted to access a `ref` prop, since it was not possible to get a reference to one. `forwardRef` _will_ still pluck `ref` from the props object, though, since it's extremely common for users to spread the props object onto the inner component and pass `ref` as a differently named prop. This is for maximum compatibility with existing code — the real impact of this change is that `forwardRef` is no longer required. Currently, refs are resolved during child reconciliation and stored on the fiber. As a result of this change, we can move ref resolution to happen only much later, and only for components that actually use them. Then we can remove the `ref` field from the Fiber type. I have not yet done that in this step, though.
