Issue Summary

In some tenants, copying a page that contain expand(s) macro automatically add an extra data-layout="wide" parameter to its Storage Format, that didn't exist in the original (copied) page storage format.

This can cause issues later, like when using an Include Page macro that includes the Duplicated (copy) page, making the included page to not render correctly the expands.

Steps to Reproduce

1. Duplicate an existing page that contain the expand macro.
2. Check the new page Storage Format and look for the extra data-layout="wide" parameter that got added for the expand(s).

Expected Results

No extra parameter should be added to the Duplicated page when compared with the original (copied) page.

Actual Results

An extra data-layout="wide" parameter is added for the expand(s).

Workaround

If you are facing issues due to this, like when using an Include Page macro that includes the Duplicated (copy) page, making the included page to not render correctly the expands, you may replace or remove the expand from the original page before making a copy, at least until this bug is (code) fixed.
