[Interest] Strange ordering problem with ComboBox

[Shantanu Tushar]

I haven't experienced exactly the same, but I did experience that if I use
a QSortFilterProxyModel as a model for ComboBox and the sort order changes,
ComboBox doesn't update itself. (A ListView connected with the same model
updates).
