Audio file embeds have messed up thumbnails in VisualEditor.
(It was pretty difficult to find a real example, most audio embeds on Wikipedia are done using a variety of templates like Template:Listen and Template:Spoken Wikipedia. I can only hope y'all are not easily offended.)
There are a few issues:
- Obviously, the thumbnail is stretched. There is no image to be generated for an audio-only file, so the imageinfo API responds with this file regardless of the requested thumbnail size: https://en.wikipedia.org/w/resources/assets/file-type-icons/fileicon-ogg.png
- Attempting to resize the image (by dragging the corner) will instead immediately scale it to 0x0px
- "Image size" controls are present in the media dialog, but not functioning
