1473917 - Show shadow roots in the breadcrumbs

Status: VERIFIED FIXED

(DevTools :: Inspector, enhancement, P3)

Description

[Julian Descottes [:jdescottes]]

Right now the breadcrumbs will not show any element for shadow-roots.

For instance: 
- go to https://shop.polymer-project.org/
- expand: body > shop-app > #shadow-root > app-location > #shadow-root
- select iron-query-params

In Firefox, the breadcrumbs will display:
html > body > shop-app > app-location > iron-query-params

While in Chrome they display:
html > body > shop-app > #shadow-root > app-location > #shadow-root > iron-query-params

Note that for iframes neither Chrome nor Firefox display a "#document" element in their breadcrumbs.
