 FAIL Passing non-objects, Dates and RegExps for blobParts should throw a TypeError. assert_throws: Should throw for argument object "[object Object]". function "function () {
       new Blob(arg);

 FAIL A plain object with @@iterator should be treated as a sequence for the blobParts argument. Failed to construct 'Blob': The 1st argument is neither an array, nor does it have indexed properties.
