White favicon

Hello,

Why is the favicon a white thing on transparent background? https://git.pleroma.social/pleroma/pleroma/-/blob/develop/priv/static/favicon.png

This makes it invisible in most browsers. Also I do not understand what it’s supposed to be and why it’s not pleroma logo?

I thought I had a bug on my installation at first.

Also it seems this is not something which can be set in the admin UI?
