Looks like there are plenty of places that set the selectable state of a DataGridNode: var node = new WebInspector.DataGridNode({name: attribute.name, value: attribute.value || ""}, false); node.selectable = true; But DataGridNode only has a getter for "selectable" not a setter.

* STEPS TO REPRODUCE 1. Inspect any page with an image 2. Show the Node details sidebar for an image 3. Expand Attributes Section => exceptions in inspector
