` Detecting initialized properties of classes using Eslint rule`

When useDefineForClassFields:true is used, the code below becomes invalid when targeting es2022:

Cannot read properties of undefined (reading 'array') 

class Bar {
    array = new Array();
}

class Foo {
    foo = this.bar.array; // Property 'bar' is used before its initialization

    constructor(private bar: Bar) {}
}

console.log(new Foo(new Bar()))

Is there an ESLint rule that can flag this as an error?

PS: Although setting the target to EsNext triggers an error, I am looking for a different solution.
