Potential bug in test_dart.html? You should see: A: [From A]
B: [From A]
C: [From A] Instead I see: A: []
B: []
C: [] To fix, remove the initialization of the published attributes. IOW don't set `@published String type = ''` to a blank string FWIW, looks like test_js.html works.

Lifecycle callback when an element leaves a view. The JavaScript version works (I see I leave you now in the console) but the Dart version doesn't display the 'I leave you now'. Note: the x-b and its children do disappear from the page. This code is about removed() in x-c not firing.
