interface HttpProgressEvent {
  readonly lengthComputable: boolean;
  readonly loaded: number;
  readonly total: number;
}

Mirrors the ProgressEvent fields loaded, total, and lengthComputable. loaded counts bytes read from the upload or download stream, not bytes acknowledged by the server. Download bytes may already be decompressed. Unknown lengths use total: 0 and lengthComputable: false. A download total is computable only with a positive Content-Length and an absent or identity Content-Encoding; compressed downloads, other encoded responses, and bytes exceeding Content-Length have an unknown decoded length. A streamed FormData upload also has an unknown total unless a valid explicit Content-Length supplies it. Other unknown-length streams use the same 0 / false fields.
