invalid code generated for preact useRef

[nitsky]

I am observing that esbuild is emitting the invalid code shown below. h3 corresponds to useRef and o3 corresponds to currentHook from preact/hooks: https://github.com/preactjs/preact/blob/3017d91a69f1b52bb89be118e22f4778cb82dd02/hooks/src/index.js#L175. It seems esbuild is choosing to split off currentHook into a separate chunk even though its value is reassigned in useRef. I am using esbuild v0.6.11 and the bundle and splitting flags.

import {
  o3,
} from "./chunk.frH4ZD-M.js";

// ../node_modules/preact/hooks/dist/hooks.module.js
function h3(n3) {
  return o3 = 5, _3(function() {
    return {current: n3};
  }, []);
}
