this is probably going to fail in dart2js unless we declare bar being used
somewhere, you can work around it by adding a computed expression above like:

@ComputedExpression('baz')
var ignore => readValue(#baz);

Done.

+    expect(injectDiv.innerHtml, '<span>baz</span>');
+
+    xFoo.bar = 'bat';
+    return new Future(() {}).then((_) {
+      expect(injectDiv.innerHtml, '<span>bat</span>');
+    });
+  });
+});
