this turned out to be a bug in the test: "attributes" is read from the template.
I run into this now that errors are thrown async (not just logged)

hmmm, I'm confused now :(. I thought we shouldn't need to add @reflectable

soon: we are still not generating code in polymer, so this is still necessary
because our tests are using the mirror-based implementation of smoke.

Once we flip that bit, we can try removing this again. Added a TODO
