Base state is not reconciled if read from draft and reassigned

🐛 Bug Report

const {produce} = require("immer");

const bar = {};
const foo = {bar};

console.log(
  produce(foo, (draft) => {
    // comment next line out and it works as expected
    draft.bar;
    draft.bar = bar;
  }) === foo
);

Accessing draft.bar and then setting draft.bar to the same value breaks immutability. This appears to be a regression starting from version 7.0.0 onwards. Works as expected in 6.
