UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.75 Safari/537.36

Steps to reproduce the problem:
1. Update Google Chrome from hamburger menu

What is the expected behavior?
Previously hidden extension buttons to remain hidden, and extensions that did not require a button to not be visible ever.

What went wrong?
After Google Chrome restarted after an update, the Chrome Menu displayed a bluish grey background and *all* extension buttons were visible, including previous manually hidden buttons, and extensions that don't require a button in the first place.

Did this work before? N/A 

Chrome version: 49.0.2623.75  Channel: beta
OS Version: OS X 10.11.3
Flash Version: Shockwave Flash 20.0 r0

I first noticed this a few days ago when I updated Chrome on my laptop (OS X 10.10) and brushed it off as not updating it in a long time.  Today, it happened again on another computer running Windows 10 and another running OS X 10.11.

Extensions that add an icon/button to the right hand side of the location bar are displayed as buttons in the Chrome Menu instead.  For example: Bookmark Manager (https://chrome.google.com/webstore/detail/bookmark-manager/gmlllbghnfkpflemihljekbapjopfjik)
