Mobile: Favicon is not used when making a shortcut on Home screen

• Tor Browser and Tor Broswer (Alpha):
• Press the three dotted button in the top right,
• Select "Page >",
• Select "Add to home screen".
• A button on the home screen appears, but is missing the favicon.

Would the proper behaviour be to download the largest favicon possible and then resize it down on the client-side to avoid resquesting an icon dize that might identify the client os?

NOTE: Old Orfox appears to function correctly, in that the icon is used and it appears brilliant and sharp (ie. high-resolution).
