Setting macro width does not keep the setting after editing

Issue Summary

When a Confluence page is fixed width, macros gain the option to control whether they display as:

• Center
• Wide
• Full width

When the JIRA Road Map macro is edited, by clicking the pencil icon to open the ‘Edit JIRA Road Map macro’ dialog and then clicking the Save button, the “full width” setting is retained.

However when the Sequence Diagram macro is similarly edited, it reverts back to “center”. We would like the behaviour of the Sequence Diagram macro to match the JIRA Road Map macro, and retain whatever display setting was already selected after editing.

This is reproducible on Data Center: no

Steps to Reproduce

1. Make a page "fixed width".
2. Insert the Sequence Diagram macro.
3. Set the macro width to "full width"
4. Edit the macro.

Expected Results

The macro retains "full width" setting.

Actual Results

The macro is changed to "back to center" setting.

No exceptions are shown in the browser console.

Workaround

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