First off, thanks a lot for this great prism extension! I've been using it in an online bibtex editor context and it's been working great for the most part, however I've noticed that it sometimes hangs itself when trying to parse invalid bibtex, which of course happens a lot during editing.

I've been able to reliably reproduce this by starting a bibtex file with:

@article{newpaper,
  title=

@article{existing,
  title={my old title}
}

Somehow, at this particular moment in editing, the plugin appears to go into an infinite loop, because the tab's CPU goes to 100% and freezes completely.

Any idea whether this can be fixed? Simply punting and giving up would be fine in my context (i.e., only highlight when valid).
