Description
Originally reported on Google Code with ID 1280
What steps will reproduce the problem?
1. Start a HtmlUnit driver that has Firefox capabilities.
2. navigate to a page that has jquery on the page.
3. get a List of web elements by running a findElements selector.

What is the expected output? What do you see instead?
The expected output would be to get the list of WebElements back as an array.
