Steps to reproduce:
(1) Open a tab and navigate to any URL;
(2) Run the following code in the Console of Devtools:
(3) Then this code would be evaluated successfully without throwing any exception.
This code is evaluated successfully without throwing any exception.
FileReader.readAsArrayBuffer asks a Blob type object as its parameter, but Webkit doesn't check the type of the param in this code. A TypeError should be thrown in this code.
BTW, both Chrome and Firefox throw exceptions:
Chrome: `VM1217:1 Uncaught TypeError: Failed to execute 'readAsArrayBuffer' on 'FileReader': parameter 1 is not of type 'Blob'.`
Firefox: `Uncaught TypeError: FileReader.readAsArrayBuffer: Argument 1 is not an object.`

Indeed. I'll resync the WPT tests in a follow-up as we seem a bit out of sync.
