Fix issue #23

[bicknellr]

Could you add a test or two for this?

[davidrissato]

Ok, I'll add them in a couple days.

@bicknellr I'm trying to implement some tests to this problem, but I believe I need to go deep in the shadowed elements to expose the problem. I'm not an expert in HTML tests. Can I do that? I think if I do this way my tests will fail in case of internal refactoring.

[bicknellr]

I've been trying to group together a handful of fixes in #44 and I've added a test there for the issue this PR is addressing. I think you're right, there doesn't appear to be a good way to test this without reaching into the internals. :/

[davidrissato]

@bicknellr Yes. So I'm a little bit confused. Will you use this pull or have you already added these changes in #44? Do you still need that I add tests here?

[bicknellr]

@davidrissato Sorry about stepping on your toes here! It seemed like a few different issues could be resolved by refactoring iron-image to use a single img element internally - #23 being one of them - so don't worry about pushing tests for this PR. However, it would be great to get your confirmation that #44 correctly tests for / fixes #23.

[davidrissato]

Ok, no problem. This solution was based on a single img element too, so I believe you are addressing it as well. I'll check #44 and verify if it really fixes all #23 reported problems.
By the way, should we close this pull request?

[bicknellr]

Sounds good, thanks!
