That's right - we implement method_missing to avoid the prefix present
in HtmlUnit.
You can use Ruby's reflection features to see a list of what methods
an object responds to:

  >> browser.div(:id, "gbar").javascript_object.methods - Object.methods
  => ["jsx_set_align", "jsx_set_align__method",
"jsxGet_align__method", "jsx_get_align", ...]
