Renaming hierarchical vocabulary will rename only the child vocabulary

• I create a hierarchical vocabulary named toto
• I create a doc type with a widget Multiple chained vocabulary bound on toto
• I deploy my studio project
• I rename it as toto2
• I change the binding into toto2 in my document type
• I deploy my studio project

Problem

• When I display my creation layout an error occurred telling that toto is not found
• in the extension.xml I see the widget is bound on parent vocabulary named toto and child vocabulary named toto2
