Description Nolan Lawson 2014-10-12 06:54:52 PDT 
Created attachment 239703 [details]
Test case in pure HTML

1. Create a Blob
2. Create an object URL for the blob
3. Fetch with XHR

Expected:

content-type and content-length should match the blob's type and size.

Actual:

Safari gives null for both.

Details:

I've provided a live test and also attached it.

Notice that in Firefox and Chrome, the correct content-type and content-length are given, whereas in Safari it's given as null and null.

Tested in Safari 7.1 (9537.85.10.17.1).
