Fetch API Missing Redirected Property

[arjunyel]

TypeScript Version: 2.4.2

Code

fetch('flowers.jpg').then(function(response) {
  if(response.redirected) {
//  Property 'redirected' does not exist on type 'Response'.
    return response.blob();
  }
  throw new Error('Request was not redirected!.');
});

Expected behavior:

The response from a fetch API request has a redirected property per MDN

Actual behavior:

The definition does not exist
