DOM inspector mispositions highlights for elements in iframe whose container is position:fixed
If you create a div that is positioned with, then put an iframe in it, and inspect an element in the iframe, the inspector displays a highlight and several measuring lines around the inspected element. If you then scroll the viewport, the iframe and everything inside it correctly stays in the same place, but the inspector highlight and measuring lines are scrolled. See this jsfiddle (doesn't work in the normal jsfiddle interface because it wraps the example in another iframe, and so what's being scrolled isn't the viewport).
