I have checked the following:

• I use the newest version of bruno.
• I've searched existing issues and found nothing related to my issue.

Describe the bug

Where this came up:
It was possible to extract a sub-string from the value saved in an environment dependent environmental variable (saved in the .env file).

Breakage:
Now if I use define a Pre Request Var in the VARS tab and load it in my Script:
const cookie = bru.getVar('Cookie');
then it is no longer resolved:
console.log({cookie});
returns {{cookie}}, where it used to return the value of the cookie env var, which I could work with in the script.

.bru file to reproduce the bug

const envvar1 = bru.getVar('ev1');

console.log({envvar1});

req.setHeader("test", envvar1);
console.log(req.headers);
