Chrome Version       : <Copy from: '48.0.2564.116'>
URLs (if applicable) : any
What steps will reproduce the problem?
(1) Create simple Chrome extension with "tabs" permissions.
(2) Put the following code to popup.js and execute this:
---
chrome.tabs.create({url: 'http://google.com'}, function(tab) {
alert(tab.id)
	}
)
---

What is the expected result?
I expect to see alert with tab.id value as a result of callback function.


What happens instead?
New tab opens, but callback function doesn't work.
If we will try to execute following code:
---
chrome.tabs.create({url: 'http://google.com', active: false}, function(tab) {
alert(tab.id)
	}
)
---
callback function works correctly.

BTW, "chrome.tabs.create()" creates active tab by default. This problem not reproduced in previous version of Google Chrome (I tested on 46.x).
If this is a new feature, official API documentation https://developer.chrome.com/extensions/tabs#method-create doesn't contain any information about it.
