VS code debugging, why is this undefined?

Question

Google Chrome

When debugging from VS code via chrome debugger extension this is undefined even though the code runs as it should with no errors

class Q {
    constructor() { 
        this.arr = [1,2,3]
    }
    log(e) {
        console.log(e)
    }
    test() {
        this.arr.forEach(e => {
            this.log(e); // this undefined в отладчике!
        })
    }
}

const f = new Q().Test()?

What can be wrong? maybe something needs to be specified in the config file?
