Console - Wrong response content type when downloading hippo:text on asset resource

If you click on download link on hippo:text field of a pdf asset document, it may open it in a browser tab or window as a PDF document. So, it doesn't show the content properly unless you download first and open it with text editor.
The real content of hippo:text is just text/plain type content.
Therefore, it would be more ideal that it responds it with 'text/plain' mime type on hippo:text content (also maybe with .txt file extension. e.g, TestDocument.pdf.txt').
