TypeScript code suggestions include inaccessible private fields from base classes

[yume-chan]

Type: Bug

For the following code:

class A {
    #v = 0;
}

class B extends A {
    f() {
        v // here
    }
}

Invoke "Trigger Suggestion" at comment position, it will include #v (this.#v), which is inaccessible in class B.

This issue doesn't happen in TypeScript playground, only in VSCode.
