Creating a slider in a wxPython sized panel incorrectly displays the labels as shown here:

The following is the smallest program I could write to demonstrate the problem.

from typing import cast

from wx import App
from wx import DEFAULT_FRAME_STYLE
from wx import FRAME_FLOAT_ON_PARENT
from wx import ID_ANY
from wx import SL_AUTOTICKS
from wx import SL_HORIZONTAL
from wx import SL_LABELS
from wx import Slider

from wx.lib.sized_controls import SizedFrame
from wx.lib.sized_controls import SizedPanel

WINDOW_WIDTH:  int = 400
WINDOW_HEIGHT: int = 200


class SliderBugApp(App):

    def __init__(self):
        super().__init__()
        self._frameTop: SizedFrame = cast(SizedFrame, None)

    def OnInit(self) -> bool:

        title:          str        = 'Demo Buggy Slider'
        frameStyle:     int        = DEFAULT_FRAME_STYLE | FRAME_FLOAT_ON_PARENT

        self._frameTop = SizedFrame(parent=None, id=ID_ANY, size=(WINDOW_WIDTH, WINDOW_HEIGHT), style=frameStyle, title=title)

        sizedPanel:  SizedPanel = self._frameTop.GetContentsPane()
        slideStyle:  int        = SL_HORIZONTAL | SL_AUTOTICKS | SL_LABELS

        Slider(sizedPanel, id=ID_ANY, value=100, minValue=25, maxValue=100, style=slideStyle)

        self._frameTop.Show(True)

        return True


testApp = SliderBugApp()

testApp.MainLoop()

Does anyone have any thoughts?
