Issue Summary

When we have an Expand macro that contains an Attachments macro within the expand box, it gets the width changed after saving the template - it can be saw editing the template after saving or creating a new page using this template.

Environment

• Cloud
• New Editing Experience

Steps to Reproduce

1. Create a new template or edit an existing one;
2. Add an Expand macro;
3. Inside the expand box, add a Attachments macro - note the width, centered as default;
4. For comparing reasons, add another Expand macro with some random text;
5. Save the template;
6. Edit this template or create a new page using it;

Expected Results

The Expand macro with the Attachments one keeps the same width as the other expand.

Actual Results

The width of the first added expand gets slightly bigger than the original size.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
