WEHM artwork (favicon) link not working

[garuffalo]

I use the "Shortwave" radio app to stream internet radio. One of my favorite stations, WEHM - 92.9 & 96.9 FM - Long Island, is not displaying any artwork. On the station listing on radio.browser.info, the favicon is showing and there is a working link to the image, yet Shortwave is not showing any artwork. It shows artwork for other stations.

The station is not broken. Everything else works fine..

I contacted the developer of Shortwave, who instructed me to open an issue here.
