Replace `image_tag avatar_icon_for_user` with `Pajamas::AvatarComponent` in `app/views/shared/milestones/_participants_tab.html.haml`
One or more avatars in in
app/views/shared/milestones/_participants_tab.html.haml
are rendered with image_tag avatar_icon_for_user
. Instead, we should use Pajamas-compliant Avatar ViewComponent
Thank you!
