Monaco Editor Playground Code

class Test<T> {
}
class Test1 {
}
class Test2 {
}

declare class Global {
    static tryGetBean(bean: string):string;
    static tryGetBean(bean: number):number;
    static tryGetBean(bean: Test<string>):number;
}

Global.tryGetBean('123');
Global.tryGetBean(123);
let test1: Test<string> = new Test<string>();
let test2: Test<number> = new Test<number>();
let test3 = new Test1();
Global.tryGetBean(test1);
// why no errors
Global.tryGetBean(test2);
Global.tryGetBean(test3);

Reproduction Steps

Global.tryGetBean method called without type check.

Actual (Problematic) Behavior

no errors

Expected Behavior

Global.tryGetBean(test2); Global.tryGetBean(test3); report should error

Additional Context

noStrictGenericChecks: false, noImplicitAny: false,

this isnt a monaco issue TS is structurally typed and only compares properties, but Test has none e.g. with class Test<T> { value: T; } it would error see https://www.totaltypescript.com/the-empty-object-type-in-typescript
