XYplorer Beta Club

In (Windows) File Explorer the thumbnails for MKV (Matroska Video) and MKA (Matroska Audio) files are correctly shown. In XYplorer the thumbnails are shown for MKV but not for MKA files. Can be replicated.

XYplorer 27.20.1400
Windows 10 Pro 22H2
Screen Scaling 125%

For me Thumbnails are shown for this file types.
In my case they are provided system-wide through the K-Lite codec pack.
Normally mka audio files don't have thumbnails.
