IVector<T>, etc. function arguments don't allow arrays as arguments in generated TypeScript type definitions

[dunhor]

E.g. the following declaration:

static Windows.Foundation.Collections.IVector<Boolean> ReturnSameBoolVector(Windows.Foundation.Collections.IVector<Boolean> vector);

gets projected as:

public static returnSameBoolVector(vector: Windows.Foundation.Collections.IVector<boolean>): Windows.Foundation.Collections.IVector<boolean>;

This should presumably be:

public static returnSameBoolVector(vector: Windows.Foundation.Collections.IVector<boolean> | boolean[]): Windows.Foundation.Collections.IVector<boolean>;

because we allow arrays as arguments to functions that expect IVector<T>/IVectorView<T>/IEnumerable<T>
