so I noticed last week that the Flow builds were getting deprecation warnings from the test framework saying  "Locating textareas with '#text_field' is deprecated. Please, use '#textarea' method instead."

I don't like being deprecated, but upon updating the test, to my surprise, the page_object gem could no longer see the element.  

I filed an upstream bug for this: https://github.com/cheezy/page-object/issues/248

In the meantime, let's keep using the text_field locator as long as it keeps working for us.
