Object properties are incorrectly erased when using hoist_props

[ThomasJClark]

Describe the bug

When some, but not all, properties of an object are accessed, other properties are erased, even if the object itself is exported.

Input code

const obj = {
    foo: 1,
    bar: 2,
};

console.log(obj.bar);

export default obj;

Config

{
  "jsc": {
    "parser": {
      "syntax": "ecmascript"
    },
    "loose": false,
    "minify": {
      "compress": {
        "hoist_props": true
      }
    }
  }
}

Expected behavior

The export is equal to { foo: 1, bar: 2 }

console.log(2);
export default {
    foo: 1,
    bar: 2
};

Actual behavior

The export is equal to { bar: 2 }, and foo is erased from the compiled code.

console.log(2);
export default {
    bar: 2
};

Version

1.3.70, 1.3.71

Additional context

This only occurs when at least one property of obj is accessed. Without the console.log, all properties of obj are correctly included.
