Hello Keegan, For me, it is only happen on plugin, theme components. When I click the topic list avatar than click the other (plugin and TC) avatars the outline disappear.
I tried it several browsers and same result.
Android 12
Chrome 106.0.5249.65
Firefox 105.1.0
MacOS 12.4
Chrome 105.0.5195.125
Firefox 105.0.1
Thank you
