Created attachment 280099 [details] Screenshot showing an element within a shadow tree reporting child layers outside of the element's subtree Steps to reproduce: 1. Open the iOS Simulator and open Safari 2. Go to http://www.apple.com/apple-events/march-2016/ 3. Open the Web Inspector on OS X to inspect that page 4. Target the <video> element 5. Reveal its shadow tree 6. Drill down a bit inside that tree 7. Show the Layers sidebar There are too many elements in that sidebar, some are outside of the subtree hierarchy of the selected element for instance, and some seem to be duplicated.
