New UI breadcrumbs don't refresh the page anymore
I used to use the breadcrumbs to refresh the current page (since the resource tree doesn’t get redrawn using the on-page refresh buttons). This functionality no longer works.

Parts of the page don’t automatically update just because something changed that we’re expecting. New properties showing up because of discovery, new instances because of discovery, alerts clearing, etc. In the past, it was handy to use the breadcrumbs to initiate that refresh because it would redraw the resource tree exactly to where you were at. A page refresh would do the same thing, but would not always expand the portion of the tree you were looking at, leading to extra clicks.
