TextAttributes in OBDefinitions

Hello Squeakers,

I am trying to add TextAttributes to the text which is shown in the  
definition panel of OBBrowsers. My attempt to add TextAttributes to  
the results of #text methods of OBNodes had no effect.

E.g. I changed OBUPackageVersionNode>>text to:

        ^ package longDescription asText allBold

and expected to read the details of package versions in bold text.  
But nothing changed.

Is there a way to do this?

Best regards,
Robert
