 Thanks @mishig25.

Just one question: is it expected to have the deprecated box right edge not filling all the page width (contrary to the added box)? > Just one question: is it expected to have the deprecated box right edge not filling all the page width (contrary to the added box)?

Yes, that is expected 😊 because the depreacted box is being bounded by its parent box (the box for `name` argument in the screenshot above)
This PR updates the builder docstring with deprecated/added directives for arguments name/config_name.
