Incorrect SetMinSize called in wx/ui_panel.py's FillPanel.add_items

I have tried to create my own widget through writing a custom editor (in particular, setting the self.control in the init() function). I've encountered this issue where the minimum size of the wx widget is ignored. It seems like at around line 1091 of wx/ui_panel.py (inside the add_items() function) would try to calculate the height purely from the item.height and item.width. Should this take into account of the control.GetMinSize() as well and do a max on the two (control's min height and item's height)?
