panic: Expected scope (6, _), found scope (7, _)

[softwareCobbler]

I recently upgraded an old project to 0.18.11 and got hit with

panic: Expected scope (6, _), found scope (7, _)

It bisects down to changes introduced from 0.17.5->0.17.6, and starting with 17.6 seems to be consistently present until now.
The following contrived case is enough to reproduce the error:

(() => {
    const enum E { a };
    () => E.a
})

Some output showing behavior across versions:

C:\Users\anon\dev\esbuild-bug>npm install esbuild@0.17.5
C:\Users\anon\dev\esbuild-bug>npx esbuild --version
0.17.5

C:\Users\anon\dev\esbuild-bug>npx esbuild Repro.ts
() => {
  let E;
  ((E2) => {
    E2[E2["a"] = 0] = "a";
  })(E || (E = {}));
  ;
  () => 0 /* a */;
};
