While investigating this VitalSource Bookshelf bug:
REGRESSION: VitalSource Bookshelf registering for a new account fails in TOT
We are adding a workaround for this application, but we need to notify VitalSource, so they can change their code.
They seem to be using these calls to contruct a url string that contains the form elements' values. But they should just be able to use the ObjC DOM calls to submit the form directly.
If they keep their current code, they should just send strings like "document.forms.elements.length"
