任何文本字段中的右键单击上下文菜单都会导致程序崩溃,并出现错误“m\u menuDepth>0”?

我注意到,当右键单击wxPython小部件中的文本字段时,如果用户选择 Insert Unicode control character

wx._core.wxAssertionError: C++ assertion "m_menuDepth > 0" failed at ..\..\src\msw\toplevel.cpp(1545) in wxTopLevelWindowMSW::DoSendMenuOpenCloseEvent(): No open menus?

The above exception was the direct cause of the following exception:

SystemError: <class 'wx._core.CommandEvent'> returned a result with an error set

下面是一个抛出错误的示例代码;

import wx


class Program(wx.Frame):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

        self.panel = wx.Panel(self)
        self.sizer = wx.GridBagSizer(0, 0)
        self.panel.SetSizer(self.sizer)

        self.text_ctrl = wx.TextCtrl(self.panel)
        self.sizer.Add(self.text_ctrl, wx.GBPosition(0, 0))

        # Needed, because there probably has to be some events which
        # can be processed for the error to show before closing the program.
        # Without this the error only appears after exiting.
        self.text_ctrl.Bind(wx.EVT_TEXT, lambda e: print("text changed"))

        self.sizer.Layout()
        self.Show()


app = wx.App()
program = Program(parent=None)
app.MainLoop()

如果不从头开始重做上下文菜单,不完全禁用上下文菜单,不包装大量内容,如何防止此错误 try-except (真是个坏习惯 wx._core.wxAssertionError ,因为它们通常是致命的)?
