Include Page macro breaks the layout of the source page's contents

Issue Summary

Environment

• Confluence Cloud
• New editor

Steps to Reproduce

1. Create a page with different types of contents and formatting
2. Set the width to the default one (narrow)
3. Create another page and use the Include Page macro to include the first page

Expected Results

The first page should be rendered inside the second page without change

Actual Results

It changes the layout of some of the contents

Notes

The changes also include:

• Page include automatically adds a school bar that cuts off part of the page unless you scroll left to right.
• The Panels (Info, Note, Success, Warning, Error) lose their styles
• Bullets (from bulleted lists) are cut in half
• Columns lost their original width;
• Tables renders in legacy editor, instead of the current editor, and with a different size;
• Breaks/Don't render Smart Links

Workaround

The available workaround is to set the second page's layout to wide, but this can cause other issues with the layout.
