Steps to reproduce the problem:
1. Add a css varibale and see its value in inspector
2. Change it's value using js
3. See if the displayed value updates

What is the expected behavior?
Inspected CSS variable value should reflect the current value of the variable real-time, just like other CSS attributes.

What went wrong?
It only shows statically set value of the variable. 
Resizing DevTools window (a redraw?) updates the value.

A screen capture gif is attached.

Did this work before? No
