Two import statements exposes variables

The problem

Trying to obfuscate the following code:

import ok from 'lib1';
import ok2 from 'lib2';

let simple = null;
let test = null;

Results in:

import _0x19aaee from'lib1';import _0x279d2c from'lib2';let simple=null;let test=null;

Exposing the let simple=null;let test=null; even if Rename Globals is enabled.
It seems to me that it is not right.

But with only one import statement like:

import ok2 from 'lib2';

let simple = null;
let test = null;

Results in:

import _0x408065 from'lib2';let _0x39e0d2=null;let _0x5f02c4=null;

I think this is correct 👍
