Classes with constant computed property names aren't three-shaken

[unilynx]

The following code is not being tree shaken awy:

const prop = "prop";

class Money {
  [prop] = true;

  constructor() {
  }
}

.bin/esbuild test.ts --minify --bundle --format=esm --target=esnext returns: var c="prop",r=class{[c]=!0;constructor(){}}; - I'd expect nothing

Setting the prop to a Symbol() or Symbol.for(...) (which is what I was actually trying to do) doesn't work either

If I replace prop with a constant it does work:

class Money {
  ["prop"] = true;

  constructor() {
  }
}

(no output)
