wx.lib.agw.aui.AuiNotebook => Tab drag/drop bug

If you want drag-and-drop a tab of a wx.lib.agw.aui.AuiNotebook the 
application hangs after releasing the left mouse and the following error 
message occurs.
(Environment: Python 3.5.2 | 
wxPython_Phoenix-3.0.3.dev2680+55dda48-cp35-cp35m-win32.whl | Windows 10)

Traceback (most recent call last):
  File "C:\Program Files (x86)\Python 
3.5\lib\site-packages\wx\lib\agw\aui\auibook.py", line 2023, in OnLeftUp
    self.ReleaseMouse()
wx._core.wxAssertionError: C++ assertion "!wxMouseCapture::stack.empty()" 
failed at ..\..\src\common\wincmn.cpp(3319) in wxWindowBase::ReleaseMouse(): 
Releasing mouse capture but capture stack empty?

When I look into the code I see the following there:

2022            if self.HasCapture():
2023                self.ReleaseMouse()

Very surprising, because the mouse releasing is checked before the call!? I 
have no idea why that exception raised. With python 2.7 and wxPython 
3.0.2.0 this code makes no problems.

A similar problem I have sometimes when I move the whole application 
window. Then I get the following error message.

Traceback (most recent call last):
  File "C:\Program Files (x86)\Python 
3.5\lib\site-packages\wx\lib\agw\aui\framemanager.py", line 9219, in 
OnLeftUp
    self._frame.ReleaseMouse()
wx._core.wxAssertionError: C++ assertion "!wxMouseCapture::stack.empty()" 
failed at ..\..\src\common\wincmn.cpp(3319) in wxWindowBase::ReleaseMouse(): 
Releasing mouse capture but capture stack empty?

But that error only appears very seldom and not predictable. But the 
problem is the same as above => with calling the method ReleaseMouse() 
despite of a previous HasCapture() check.

Hope somebody can help me. Thanks!
