Header name for inverse properties in ask queries

From semantic-mediawiki.org

If I display the value of an inverse property as in {{#ask: [[...]] | format=table | ... | ?-Property name=Header name}}, the table fails to display the specified header in the table. The header is blank while regular property value headers are shown as given. Note that the values of the inverse property are all shown and are correct. It is only the column header that is not shown.

Is this a bug?

Note that the workaround is to use format=template and construct the table myself. I use the intro template to name the headers correctly, and user {{#show:}} to get the properties I want in the individuals rows. However, I see no reason why format=table should fail to display the given header name.
