Steps to reproduce the problem:
1. Open Chrome with Material Design enabled
2. Place windows in front of vibrant photo
3. Observe translucent of tab strip background

What is the expected behavior?

What went wrong?
It looks like background is translucent (I was wrong about my comment in  issue 595861  comment #6), but according to spec from  issue 595861  (comment #3) translucent of background is more translucent. 

Did this work before? No
