I think we have a bug for when trying to spawn a Hierarchy browser or
System browser from the ObjectExplorer -- its failing one of its own
assertions. If I comment out the assertion, it opens browser on the
parent object instead of the selected object.
To reproduce: Simply explore the 'preferencesDictionary' class-inst
var of Preferences, and then select one of the PragmaPreferences, then
press Command+h. Boom.
