Complete CLI command or minify() options used

{
  "module": false
}

terser input

function g() {
  var e = [];
  e[1] = 1;
}

function f() {
  var e = [];
  e[0] = 0;
  e[1] = 1;
}

terser output or error

function g(){}function f(){var n=[];n[0]=0,n[1]=1}

Expected result

Given that terser is able to remove e in g, I would expect it to also be able to remove e in f:

function g(){}function f(){}
