Steps to reproduce the problem:
1. Open Firefox' Dev-Tools
2. Select an element which has its display-property set to 'grid'
3. Click the 'grid' icon right next to it
4. Inspect your element

What is the expected behavior?
Chrome should match Firefox' behaviour UI/UX-wise in this regard. It's fairly helpful and improves understanding this new display-property. To improve this further one could change this set properties by dragging the striped areas and dotted lines (see attachement).

What went wrong?
Feature is not yet implemented.

Did this work before? No
