IMAGE_QUALITY_BOX_AVERAGE is broken

Operating system: Windows 10, x64
wxPython version & source: 4.2.1a1 (build artifact from 24 Dec 2022)

Description of the problem:
When I Rescale a wx.Image using wx.IMAGE_QUALITY_HIGH, sometimes the image disappears (= becomes fully black). I think this happens when it's downsizing. When I specify wx.IMAGE_QUALITY_BOX_AVERAGE, it always disappears. I suspect wx.IMAGE_QUALITY_HIGH picks wx.IMAGE_QUALITY_BOX_AVERAGE when downsizing, and that wx.IMAGE_QUALITY_BOX_AVERAGE is broken.
