UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.62 Safari/537.36

Steps to reproduce the problem:
1. open new desktop
2. open 2 chrome browsers
3. hold the green expand icon (top left) to snap browser to half screen size.
4. Snap second browser to other half of screen size.
5. click Red X (close) icon to close one of the browsers
6. from another workspace open a 3rd browser and pull into the previous workspace.
7. the browser that was pulled in has a grayed out tabs bar, with no functionality.

What is the expected behavior?
expected to have access/functionality to the tabs and close/min/max icons.

What went wrong?
The tabs bar is now grayed out.  not allowing the user to navigate previously opened tabs or creating new tabs.  this bar also contains the red/yellow/green icons that close/minimize/maximize.

I have gotten the same grayed tabs bar when simply trying to maximize the browsers size, however i cannot replicate this.

Did this work before? N/A 

Chrome version: 62.0.3202.62  Channel: n/a
OS Version: OS X 10.13.0

I cannot get a similar result from a mac running sierra OS.
