Gutenberg PR #80484 colors the Notes avatar ring only while that person has a connected RTC session for the document; when they disconnect, the ring turns gray but the avatar stays.
Presence-api's Who's Online widgets instead drop an entry entirely once its TTL expires.
Worth deciding whether presence-api's avatar-stack surfaces (Who's Online widget, network dashboard widget, admin bar) should adopt a similar gray/active state, or whether TTL-based removal is the right behavior here.
