it works, but it generates warnings on STDERR when selecting on any view that includes the blockly partial (due to the way we send some escaped javascript through haml). i added a [comment](https://github.com/code-dot-org/dashboard/pull/746/files#diff-10d66232b09d59152aa7db39bce2f0c3R230) about using nokogiri as a workaround to avoid these warnings in another PR.
