current tab not highlighted when window not focused

Reported by davidmax...@gmail.com, Oct 16

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36

Steps to reproduce the problem:
1. open lots of tabs
2. select one of them - notice the current tab is slightly whiter than the others making it somewhat easy to see which one is the current one
3. switch to another window/app

What is the expected behavior?
I expect the current tab to still be indicated.

What went wrong?
The current tab becomes just like all the others. An effect of this is that I need to focus the window before I can close the tab.

Did this work before? N/A 

Chrome version: 69.0.3497.100  Channel: stable
OS Version: Ubuntu 18.04.1 LTS
Flash Version: 

It really should be more obvious which is the current tab - even when it *is* slightly whiter than the other ones, it isn't very easy to pick it out. Please consider something more obvious.

I'm not sure, but I think you did reproduce it. If you put more tabs on both windows, notice how much easier it is to pick out the 'current' tab in the focused window than it is on the non-focused window.

Perhaps the non-focused one does still have *some* highlighting, but it isn't enough to make it easy to pick it out easily. I didn't think was highlighted at all, but perhaps there is some there.

** UI Mass triage**
We were unable to reproduce this bug on ubuntu 17.10. Ubuntu 18.04 is not available with us to traige.Adding appropriate labels.
I think this issue is the same on both and you're just not noticing the difference I'm describing. It is quite subtle, as is the difference between the selected tab and the ones which aren't selected, when the window isn't in focus. 
It's possible the redesigned UI doesn't account for the wide-spread budget displays that have only 6 physical bits per RGB color channel.
On such devices the adjacent colors like those in the inactive window's title bar may look too similar physically.

Another possibility is that Chrome may be using the system-wide color for the inactive title bar background which may be a bad match for the hardcoded white color in the default UI theme.

TE@, can you cc someone from the UI team? Like phistuck@ maybe.
I don't think my display is a budget model. It's a:

seems like it has 10 bits per colour?

I have attached some screenshots.
