Status: VERIFIED FIXED

(DevTools :: Inspector, enhancement)

Description

[Nicolas Chevobbe [:nchevobbe]]

Steps to reproduce

1. Navigate to data:text/html,<meta charset=utf8><script>CSS.registerProperty({ name: "--a", syntax: "<color>", inherits: false, initialValue: "gold" })</script><style>body { background: var(--a); }</style>Hello
2. Open the inspector and go to the computed panel
3. Expand the --a node

Actual results

There's no additional data displayed

Expected results

It would be nice to display the initial-value so we know where the computed value comes from
