Steps to reproduce

I am using WINDOWS 11, I do not know how this behaves in Win10.

1. Create a new profile (or use an existing one)
2. For the icon, paste a weblink to an ico file (eg https://github.com/favicon.ico)
3. As you will see, that works fine (the icon gets shown in new tabs and in the settings menu)
4. keep winterm open
5. right-click onto the program in the taskbar
6. As you will see, the icons are not rendered here

Expected Behavior

Profile Icons are rendered the same way everywhere across the device

Actual Behavior

Profile Icons from the web are not rendered at all in the taskbar dialog
