Initial Checklist

• I understand this is a bug report and questions should be posted in the Community Discussions

Bug Description

Reproduction Steps

• Click on a Space in the Space listing
• The number of members in the top right corner is always 1, until the details sidebar is opened

Expected Outcome

Correct number of members. Ideally using the new $count=true&$top=0 query (opencloud-eu/opencloud#989)

Actual Outcome

1

In addition to that: when you add or remove members the member count doesn't update reactively.
