Be able to see the user reference in the user displayer in edit mode

For example, in the attached screenshot (from editing an xobject XWikiServletClass) we cannot see the if the user from the main wiki or from a local wiki...

When executing::

{{velocity}}
$xcontext.context.getWiki().getWikiOwner("wikifromthedescriptor", $xcontext.context)
{{/velocity}}

I get:

waihonapedia:XWiki.GerritjanKoekkoek

I would like to have a way when editing the user xproperty to see that refefence somehow. Could by a hover text or some other means.
