Pass Binary Object from UI to Background Page Will Break the Prototype Chain

Reported by shanger...@hotmail.com, Jun 7 2016 
UserAgent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0

Steps to reproduce the problem:
1. Create a ArrayBuffer/Blob in any UI page
2. Pass it to the background page of an extension
3. check it with "obj instanceof ArrayBuffer" will return false
4. use console.log to display it in the console, it still looks like a ArrayBuffer/Blob

What is the expected behavior?

What went wrong?
The prototype chain is broken. To walk around this issue, have to manually reset the prototype chain by 
obj.__proto__ = ArrayBuffer.prototype

WebStore page: 

Did this work before? N/A 

Chrome version: Version 51.0.2704.79 m  Channel: n/a
