Private members have implicit any type in generated declaration files

It seems the bug that was fixed in #36216 is happening again:
When generating delcarations for private class members, no type information is appended which causes the declaration file to generate errors when imported into a project with noImplicitAny enabled.

TypeScript Version: 3.8.3

Code

// Test.ts
export default class Test {
    private _number: number = 0;
    public str: string = '';
    private get num() { return this._number; }
}

Expected behavior:

// Test.d.ts
export default class Test {
    private num: any;
    str: string;
    private get num(): any;
}

Actual behavior:

// Test.d.ts
export default class Test {
    private _number;
    str: string;
    private get num();
}
