lib.d.ts - XMLHttpRequest - send

[janousek]

Current definition allows only string and Document argument. But it should allows BodyInit defined as:
typedef (Blob or BufferSource or FormData or URLSearchParams or USVString) BodyInit;

This regressed since 1.4, we need an additional overload:

    send(data?: Document): void;
    send(data?: string): void;
    send(data?: any): void;
