Editor bug; Audio preview textures vertically cut in half?

There seems to be a bug where the waveform texture of AudioClips are vertically halved. You can see it in the project explorer when the icon size is set to higher values.

In this image, the file on the left is stereo. Only the left channel is visible in the waveform texture.
The file to the right is mono. Only the positive values of the waveform is visible in the waveform texture.

For comparison, here are the waveforms displayed in the inspector preview window.

These screenshots were taken in Unity 2023.3.9f1.
