Hi everyone 👋

This PR introduced problem with production build, when we use in code PropertyShorthend.

I was trying to investigate this problem and I figured out that the problem is with this line.
If ecma is set to >= 6 then UglifyJS produces for example code:

const someVar = 'abc';
const testObj = {
  someVar,
};

that production build:

const testObj = {  someVar };

but should instead:

const testObj = {  someVar: someVar  };
