[Systray icon]When reaching 90% charge, an incorrect icon is displayed

In XFCE 4.20, with the Papirus icon theme, the Power Manager icon in the system tray displays an incorrect icon when it reaches 90% or more when connected to the charger. It only reverts to the correct icon when charging is complete. I've tracked down this icon; it's called image-missing.svg. This happens with all icon themes and all icon sizes (24px in my case). However, it only occurs when using the Power Manager icon in the system tray. This doesn't happen when using the panel plugin, which does correctly display the icon. To replicate this error, you must activate the Power Manager icon in the system tray and remove the Power Manager panel plugin (since if both are kept, the icon in the system tray still displays the correct icon). Then, connect the charger and charge the battery to more than 90% while keeping it connected. Translated from Spanish to English
