DataTransferItemList's iterator should yield DataTransferItem, not File

[gfx]

Pathces to lib.dom.iterable.d.ts are like this:

 interface DataTransferItemList {
-    [Symbol.iterator](): IterableIterator<File>;
+    [Symbol.iterator](): IterableIterator<DataTransferItem>;
 }

TypeScript Version: 3.0.1 (installed from npm)

Search Terms: DataTransferItem

Code

Expected behavior:

DataTransferItemList#[Symbol.iterator]() should yield DataTransferItem.

Actual behavior:

DataTransferItemList#[Symbol.iterator]() yields File.
