Mysterious Dot keeps returning on the People icon in the spaces sidebar

### Steps to reproduce

1. Upgrade from Element Desktop 1.10 to 1.11
2. Open Element Desktop

### Outcome

#### What did you expect?

No mysterious dots distracting me without good reason.

#### What happened instead?

A dot appears on the upper right corner of the People icon in the spaces sidebar.

The dot has no apparent explanation. I have no idea what it is supposed to mean or how to get rid of it. I briefly thought it might be a new message indicator, but I have no new messages.

Un-checking People on the pin-to-sidebar quick setting, and then re-checking it, gets rid of the dot temporarily, but it just returns next time I start Element.

What is this thing? Some kind of notification? What good is that if it doesn't offer any explanation or correspond to anything that warrants a notification?
