Widget Connector does not work with Google Spreadsheets or Draw documents on Confluence 5.9

Trying to incorporate a Google spreadsheet or Draw document into Confluence via the Widget connector results in no document being displayed and no error message.

Workaround for Spreadsheet and Google Draw:

• Enable Confluence HTML Macros by going to Confluence Admin > Add-ons > Select All Add-ons > Search for 'HTML', and finally the second HTML module of the Confluence HTML Macro add-on. (Important note: Enabling these macros can make your Confluence site vulnerable to cross-site scripting attacks. Please only enable if you trust your users.)
• Create a page and add the HTML macro
• Create an iframe, replacing the URL with the correct document.

• <iframe src="https://docs.google.com/spreadsheets/d/1dxSPZ07MJaD6HqAC8yqB-10xGWfYflnv1xZR3_fc38/edit?usp=sharing" noborder="0" width="95%" height="800" scrolling="yes" seamless></iframe>
