[Reg 4.2->4.3] Project tree with "Simplify Tree" is a mess

Open qtcreator. open project navigation view. collapse all and uncollapse toplevel node. The result is an unsorted mess.

Pre 4.3 it was also not great, but at least there was some kind of organization involved, smth like alphabetically sorted .pro and .pri files first, alphabetically sorted list of "leaf project folder nodes", then alphabetically sorted list of something like "resource files".
