Web Inspector: AXI: need a way for WebCore-triggered accessibility notifications to update the Web Inspector UI. For example, If an element's selected children changes, or child node is shown, the children or selected children values change. However, the accessibility node inspector does not update unless some content attribute is updated, We basically need a way for AccessibilityObject changes that don't affect the DOM to cause _refreshAccessibility() to be called.

An event in the protocol can be added to trigger a refresh in the UI.
