Siggi, try this to see if it cures your 'Document' problem.
If so, I will do a little refactoring.

Thanks Stephen, seems to work for me locally when running in chrome.

I updated https://code.google.com/p/dart/issues/detail?id=14720 with some
details about what I did to try this. I included a small example to repro the
problem and to verify it works with your fix. (FYI, when I played with this I
didn't run the patched dart2js, but I copied the hook code and in the generated
code.)
