Fixes #30782 When developers do an `if (ref.current == null)` guard for lazy ref initialization, the "safe" blocks should extend up to the if's fallthrough. Previously we only allowed writing to the ref in the if consequent, but this meant that you couldn't use a ternary, logical, etc in the if body.
React Compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
