The DOM nodes themselves seem to respect Show scroll bars: Always, but the "= $0" variable becomes hidden behind the scroll bar.

Also occurs without always-on scrollbars if you resize Web Inspector until `= $0` doesn't fit on the first line anymore, but the rest of the content does. Use of `position: absolute;` for this text seems suspicious, but changing that leads to a weird issue with the height of the blue "selected item" area until I move my cursor over it and back off of it. Need to reduce that issue to understand if it is in WebInspectorUI, or an underlying layout/repaint issue.
