In https://thelion.website/ when the avif version of the logo is loaded its transparent regions render as orange.

When opening https://thelion.website/, I see only one AVIF loaded which is https://thelion.website/profile/mermelon_profile.avif. I believe the transparency of this image is displayed correctly.

The logo https://thelion.website/logo.svg is still an SVG image. Can you please attach the problematic or put a link to it?

The current version of that website indeed renders correctly in GTK MiniBrowser. The previous version had a different design...
