Summary0002602: New SubList property Py API messes up the order of linked elements
DescriptionReassigning property of type PropertyLinkSubList via Python can result in the link order change.
The links to elements of the same object are grouped together, even if there is a link to other object in between.
Steps To Reproduce1. Open attached file.
2. in Py console:

sk = App.ActiveDocument.Sketch003
sk.ExternalGeometry = sk.ExternalGeometry
3. Recompute. Sketch003 transforms into a mess, and can't be edited.
Additional Informationsee forum thread: "Sketcher bug: reassigning external geometry breaks the sketch"

@DeepSOIC writes the reports very accurately, so it is exactly what he says it is. It is not the sketcher, it is the python API to that property, that I think it is this function void PropertyLinkList::setPyObject(PyObject *value), which is in the base application (not even a module).

So, it is a confirmed bug that has to be dealt with...

Maybe we can implement our own container class (Python sequence protocol) which returns the items in the same order as we had in the past. This container class provides a method to group the items the way how it's done now.
