openannotation/annotator#577

[mwidner]

@amandavisconti You should be able to use this change immediately. I'm already using it in Lacuna Stories. If you checkout that branch of the fork and build the src, you can drop annotator-full.min.js into sites/all/libraries/annotator, clear your js cache, and you're ready to go.

How cool! Thanks, @mwidner.
