Ancestors: Tools-ct.1089

Fixes a slip introduced with BlockClosureInspector. Make sure to reset the styler's workspace variable after switching to a different kind of inspector (i.e., in the context of a debugger). Otherwise, you might see error messages such as "MessageNotUnderstood: Inspector>>hasBindingOf:". :-)
