Order of a sitemenu is changed after editing its name

Reproducable by:
Go to the HST config editor
Go to Menu designer
Go to a menu item with siblings
Rename this item
The renamed item is places after its siblings.

Also reproducable by renaming a sitemenu item through the console.

The sitemenu items do have the mixin orderable.

Possible cause: sitemenu items don't have a translation, you directly edit the node name. Renaming a node puts a node at the bottom of the siblings.

Having a separate translation Node also helps in the rendering template with diacritics (sitemenu names like kipsaté which get JCR encoded)
