Dark square behind rounded avatar

[cadusilva]

I guess this is caused by something related to mastodon/#31966. But in the light mode, there's now a dark square behind the round avatar.

Affects: bolha.one, ursal.zone
Mastodon 4.3-beta2

Thank you for spotting this. It seems something happened with the structure indeed and border-radius doesn't cut the whole profile image for some reason. A simple border-radius: 50% should do it in the correct element but at the moment I don't have a minute to look at it. Will fix later on, PRs always welcome.
