Portfolio Scope Report Settings not preserved in iframe

Summary

When creating an iframe to use in a confluence page as covered in Sharing reports the columns selected in the report view are not preserved in the iframe once added to a page.

Steps to Reproduce

1. On a Scope report customize the column layout by adding additional columns
2. Share the report to collect the iframe link
3. Add the Link to an iframe gadget in confluence

Expected Results

The report is displayed as configured in portfolio

Actual Results

The report sets all columns back to the default configuration

Workaround

It is possible to Set the fields again from the Confluence page using the Settings cog in the rendered iframe, but refreshing the confluence page will revert the changes applied locally on the embedded report, and you will need to reset these settings between each page load
