[BUG] Return type of top-level functions are not documented

[hiranya911]

Overview of the issue

I have the following function:

/**
 * Does something.
 * 
 * @returns {string} A non-empty string
 */
export function doSomething(): string {
    return 'Hello';
}

The return type and description are not mentioned in the generated documentation:
