confluence.saveMacro is not working on the new live macro

Summary

Our Balsamiq app is using a custom macro editor.

When the user close the macro editor, the app invokes the confluence.saveMacro but:

• the macro data is not updated
• the live macro is not updated

Steps to Reproduce

1. Add Balsamiq Wireframes macro
2. Create two wireframes
3. Publish blog
4. Edit
5. In the custom macro editor, change to the next wireframe
6. Save

Expected Results

The same code functions as expected in the "old" Confluence editor.

Actual Results

Macro data are not saved.

Notes

It works on the old Confluence editor.
