func_documentation_string: These `standardize*` functions show what will happen to the output of your page methods.  For middleware authors: Be aware that these standardization functions will have been applied to the output of `next()` before you get access to it.  These functions are also exposed via `PageUtil.standardize*`. 
  This method takes in anything returned from a Page.getElements call and
  returns the elements in a standardized format: an array of EarlyPromises of
  ReactElements.
