How do I allow the Documents library in an Office 365 Group site allow ASPX pages to be viewed?

It appears that I can upload ASPX files to Documents library in a regular SharePoint site and it will render.  If I do the same to a Documents library in a SharePoint Site that was created as part of an Office 365 Group, the ASPX file will not render, but will be downloaded instead.
