Steps: 1. Open https://webkit.org 2. Inspect <body> 3. Open Computed panel in the right sidebar 4. Hover "background-color: rgb(0, 37, 61)" 5. Click on the arrow icon on the right. Expected: Styles panel open with "background-color" property selected. Actual: Styles panel open but no properties are selected. Notes: This must have regressed in the last 2 months.
