wx.lib.agw.aui Minimize pane issue

Description of the problem:
When drag a notebook page and dock it somewhere, it will not be able to be minimized.

The issues comes from the discrepancy between the paneinfo in AuiManager._panes and AuiManager._uiparts.

def OnLeftUp_DragFloatingPane(self, eventOrPt):
        ...
        # here we change the paneinfo in _panes, but Update() may not be called

        # reorder for dropping to a new notebook
        # (caution: this code breaks the reference!)
        tempPaneInfo = self.CopyTarget(paneInfo)
        self._panes.remove(paneInfo)
        self._panes.append(tempPaneInfo)

        if ret:
            self.Update()

        if tempPaneInfo.IsFloating():
            self.SnapPane(tempPaneInfo, tempPaneInfo.floating_pos, tempPaneInfo.floating_size, False)
    ...

Looks like if we move the "reorder" part in the if ret section, the problem goes away.

def OnLeftUp_DragFloatingPane(self, eventOrPt):
        ...
        if ret:
            # reorder for dropping to a new notebook
            # (caution: this code breaks the reference!)
            tempPaneInfo = self.CopyTarget(paneInfo)
            self._panes.remove(paneInfo)
            self._panes.append(tempPaneInfo)

            self.Update()

            if tempPaneInfo.IsFloating():
                self.SnapPane(tempPaneInfo, tempPaneInfo.floating_pos, tempPaneInfo.floating_size, False)
    ...
